Here's a few of my favorites.
Bret's book is probably the best. He has a great memory and can recount minute details of his matches. He also wrote it when he was on the outs with every single person in the business as well as most of his family so he buries people left and right. It also has a bit of funny lack of self awareness moments - mainly where he recounts having a three way with a couple of Japanese girls during a tour then a chapter later he wonders why his wife is so pissed at him.
Jericho's first book is a close second out of the ones I've read. It covers his early life to his start in the WWF. His other books, while they can be amusing are just collections of anecdotes (Here's this cool celeb I met, here's this cool thing I did etc.)
Backlund's book is also pretty good but he's really from a different era so you get lots of discussion about 60 minute draws and whatnot. It barely covers his heel run from the 90s, which is what I remember him from. He's a real boy scout though, he came from nothing, worked hard and did what was asked of him and was rewarded for it. I guess it makes him come off a bit boring but there's something admirable about a guy who managed to hold onto his morals and family in the pro wrestling business of that time.
The Titan trilogy (Sinking, Shattered, Screwed) is a recount of WWF 95-97). It's mainly a bunch of stories from those years taken from dirtsheets and shoots and woven together to form a narrative. It's a good read
Nitro is about the 90s heyday and fall of WCW but with a focus on the business side of things. Lots of interviews with behind the scenes staff and lesser known wrestlers that you don't hear about much.
