I actually find most of the big name streamers a bit too loud for my taste. I'd rather watch someone smaller who actually reads chat and isn't just doing over the top reactions the whole time.
Poker does have that perfect mix of skill and luck that keeps it fresh. My personal twist is I actually enjoy playing live home games way more than online now, the trash talk adds a whole different layer to it.
If you're betting on it I'd look at which side of the bracket opens up easiest after the group stage. sometimes the real winner is just whoever dodges the harder route to the final
