Yes, Tim O'Neill has always argued that the bar is raised in relation to Jesus; so that arguments which are accepted for other figures in ancient history, are suddenly inadequate for Jesus. I've never really followed this through, but it would be interesting, to see how other ancient figures are discussed in comparison with Jesus.
I think this point is often made about the argument from silence, the argument about contemporary evidence, the argument against hearsay, and so on.
The
Evidence for the historical existence of Jesus Christ page at RationalWiki goes over this argument:
There is more evidence for Jesus than for (insert famous ancient person here)
When discussing the evidence for Jesus' existence, a common claim made by apologists is that there is "more evidence for Jesus than 'X'".[179] This is often because ancient records really are sparse for the existence of some ancient kings, Pharaohs of Egypt, or other historical figures. However, what evidence we do have is higher quality than what exists for Jesus. This does not mean it is necessarily worthless, but it means it is worth questioning. Court records, birth records, even lists of property owners or tax records do not have this doubt attached. Finding a document that said "Jesus, known as the Christ, was crucified today, in the Court of..." would be this kind of evidence.
One common claim is that there are "over 5000 distinct pieces of evidence for Jesus". This number comes from counting each individual handwritten document (from full codices down to mere scraps) with New Testament text on it, including multiple copies of the same texts. The actual number is 5500 ancient fragments (dating from before the printing press) of any writings from the New Testament.[180] It should be noted that just 6.29% of these 5000 distinct pieces of evidence have been dated before the 9th century and only 48 supposedly predate our oldest intact Bibles[181]
While it is is impossible to cover all the ancient figures and events Jesus has been compared to there are a few popular ones that show just how shaky the position really is.
Sun Tzu (Sun Wu) (544–496 BC?): his very existence is debated in scholarly circles [182] despite reference in the Records of the Grand Historian and Spring and Autumn Annals which used earlier official records that haven't survived.
Confucius (Kong Qiu) (551–479 BCE) the Records of the Grand Historian used archives and imperial records as source material (which themselves have not survived). Its author Sima Qian noted the problems with incomplete, fragmentary, and contradictory sources stating in the 18 volume of the 180 volume work "I have set down only what is certain, and in doubtful cases left a blank." Moreover, Kong Qiu was the governor of a town in Lu and ultimately held the positions of Minister of Public Works and then Minister of Crime for the whole Lu state not exactly minor potions one could create a fictitious person to fill.
Leukippos (shadowy nearly legendary figure of early 5th century BCE): very existence doubted by Epicurus (341 – 270 BCE).[183]
Socrates (c469 – 399 BCE): written about by contemporaries Plato, Xenophon (430 – 354 BCE), and Aristophanes (c446 – 386 BCE).
Hippocrates (c460 – c370 BCE): written about by contemporary Plato.
Plato (428 – 347 BCE): written about by contemporaries Aristotle (384 – 322 BC), Xenophon, and Aristophanes.
Alexander the Great (July 20, 356 – June 11, 323 BCE): official historian Callisthenes of Olynthus, generals Ptolemy, Nearchus, and Aristobulus and helmsman Onesicritus where all contemporaries who wrote about Alexander. While their works were eventually lost, later works that used them as source material were not. Then you have mosaics and coins also contemporaneous with Alexander.
Hannibal (247 – 182 BCE): Written about by Silenus, a paid Greek historian who Hannibal brought with him on his journeys to write an account of what took place, and Sosylus of Lacedaemon who wrote seven volumes on the war itself. Never mind the contemporary Carthaginian coins and engraved bronze tablets.
Julius Caesar (July 100 – 15 March 44 BCE): Not only do we have the writing of contemporaries Cato the Younger and Cicero but Julius Caesar' own writings as well (Commentarii de Bello Gallico aka The Gallic Wars and Commentarii de Bello Civili aka The Civil War). Then you have the contemporary coins, statues and monuments.
Apollonius of Tyana (c15 CE - c100 CE): Often refereed to as the "Pagan Christ", fragments of Apollonius' own writings are part of the Harvard University Press edition of The Life of Apollonius of Tyana (1912) ISBN-13: 978-0674990180 as documented in Carrier's Kook article.
Boadicea (d. 60 CE): Tacitus himself would have been a 5-year old boy when she poisoned herself c. 60 CE making him contemporary to her. Furthermore, his father-in-law Gnaeus Julius Agricola served under Gaius Suetonius Paulinus during the revolt. So Tacitus was not only an actual contemporary, but he had access to Gaius Suetonius Paulinus' records and an actual eyewitness.
Muhammad (570 – c. June 8, 632 CE): Unlike the New Testament, the Quran was written during Muhammad's lifetime and there are some that say it was compiled shortly before his death. Moreover there are non-Muslim references by people who would have been contemporary to Muhammad.[184]
Now compare those to Jesus:
1) The only known possible contemporary is Paul (Romans, 1st Corinthians, 2nd Corinthians, Galatians, Philippians, 1st Thessalonians and Philemon) who not only writes some 20 years after the events but seems more intent on the Jesus in his own head than any Jesus who actually preached in Galilee. In fact, even though in his own account Paul meets "James, brother of the Lord" we get no details of Jesus' life, not even references to the famous sermons or miracles.
2) The Gospels are anonymous documents written sometime between 70 CE to 140 CE and there are no references to any of them until the early 2nd century.
As you can see from this sampling, the ancient person being compared to Jesus is generally in far better shape in terms of documentation.

As the above show the argument is generally bogus mainly because while there are ancient people for who there is as bad or worse evidence for Jesus they are already on the 'eehhh maybe' list (Moses) or are names that the average person wouldn't easily recognize (Asklepios). Also is should be pointed out when Robert Silverberg published
The Great Doctors in 1964 he stated "If he (Imhotep) really lived at all..." showing that even the greats may not be on as firm a ground as people like to think.
