The first Covenant trilogy was tough going but it had an interesting premise driving it. Thomas Covenant was a grimy postmodern character in a sparkly fantasy world setting. It was all about the contrast, the mismatch, which many people who felt out of place in the real world could relate to. The second trilogy, the fantasy world had gone to hell, so it was a crapsack main character in a crapsack world. Much more comfortable, in a way, but even tougher going for three long books.
I missed this thread and it's far too late to tell the OP, but years before Riverworld, Farmer wrote a book called Inside Outside, which was the first book of his I ever read (essentially, by random chance). It was about people who had been reincarnated in a place they called hell, which is highly socially regulated. The physical setting is the interior of a hollow sphere, with strange gravity effects, hostile demons, and (for some reason) telephones. The reason for it all was revealed at the end, and it was kind of stupid; hell was an artificial world, a hollow-asteroid space ship, created by aliens to experiment on captured human souls. I resolved not to read any more Farmer books for quite a while, and I didn't, until the Riverworld series came out. That seemed like a really interesting premise and a good setting for adventures involving historical figures. Then came the long drawn-out ending... and it was the same ending, the same explanation, even with the same names for the factions of aliens, as Inside Outside. Fool me twice, shame on me.
Never mind the twist in the first Dragonriders of Pern novel/collection, Dragonflight, which launched the series and McCaffrey's career.

He uses time travel to get his characters out of the holes they've dug for themselves.
