From completely personal opinion and that of close friends: x265 movies look way cleaner while having way smaller file sizes. Also it's the best tradeoff between quality/filesize by factor of 2 or more. I'd personally notice artifacts in x264 movies unless they were over 7gb in size. With x265 i'll grab a 3gb version of a movie in a heartbeat (well a few heartbeats on gigabit fiber :) and not worry about picture quality at all. at 15gigs or more for a 1080p movie x264 is pretty much perfect, unless you really want to see the film-grain.
