The first three of Dennis E Taylor's Bobiverse tales, definitely: easy reads and the most compelling that I have read for a long while. The next ones may be too - I just decided to take a break before continuing.

Also Dan Simmon's Hyperion for it's breadth of styles if nothing else.

The early Murderbot diaries by Martha Wells. After the first five there were some elements that started to get a little repetitive, so I took a break there. I expect to enjoy them again when I restart though.

And then The Road, of course, which is by far the most literary, and probably The Player of Games so far from the Culture tales.

The least favourite would be This is How You Lose the Time War by Amal El-Mohtar and Max Gladstone, which I found naïve and unconvincing.
