I hate screamer and mumbled streamers so won't watch any of them if I can do literally anything else. But I frequent "Call me Kevin" on Youtube, his edited videos are production quality but in my opinion his streams are top notch too.
For some reason I can't get into his current stuff. I liked it before he did the face cam stuff.
RTGame, however, I'll watch just about anything he puts out.
I watch RT Games too but like Kevin's new stuff more, different strokes for different folks I guess.
