Mostly this, performance is atrocious on a lot of sites I use. I also dislike its history management, download management, auto-complete, search in address bar functionality, pocket integration, and much more. I'm sure if I were forced to spend more time with it I could possibly find configurations to customize all those things in a way I like, but even using it for a few days the easily findable settings weren't flexible enough.
