It's true that you can't pause a stream on Twitch, but Twitch allows you to save clips that are functionally equivalent to rewinding, which isn't available on YouTube. Twitch's UX&I is also much better suited to streaming than YouTube (bigger chat, multiple viewing sizes/configurations, no video suggestions).

I could go through the awkward process of making a clip every time I miss something and want to rewind a few seconds, but once I do that now I've missed even more of the broadcast and there's no way to catch up. Twitch only works comfortably for completely live viewing, watching finished VODs, or watching ongoing VODS with half an hour delay minimum.

Clips are a neat feature but they're a sharing feature, not a "help me watch" feature.
