I don't really watch any entertainment YouTube videos either, I watch Linus Tech Tips, Hardware Canucks, JayzTwoCents, Awesomesauce Network and Paul's Hardware... That's about it
Videos are fine because they're highlights - what I'll want to see, and thus I can watch them whilst being entertained for ages.
Twitch is just real-time RS. Often people standing around for ages, or I'm watching a real-time version of something I'm doing, it's just not worth my attention. Also, I've never seen a streamer who I feel I can relate to/find funny or entertaining, etc.
