Yeah, it's entertaining but surely not the "best". In the Fantasy genre I enjoyed The Expanse series ( https://www.goodreads.com/search?q=the+expanse&ref=nav_sb_no... - the TV series is a good adaptation too, but incomplete) and the The Queen's Thief series ( https://www.goodreads.com/series/43514-the-queen-s-thief ) more.

It's certainly not the best of all time. Goodreads' user base appears to have a pretty narrow demographic, though, so I don't think that any general conclusions can be drawn from opinion polls of them.
