Yeah, I guess it is different from person to person. Personally I like to analyze my HUD like that, but i understand if it isnt worth it for some people.
But streams are definitely a good way to learn, especially if you aren't a big fan of studying too much - eventhough I learn quite a bit from watching them, I never treat it as studying, as many streams also are entertaining. Even if you just want pure studying, there is also streams for that.
The most popular streamers would be people like:
Jason Somerville
Tonka
Kevin Martin
Jaime Staples
Bill Perkins
- I can recommend to check out all of these streams
Also people like Daniel Negreanu, Liv Boeree and Phil Hellmuth have been streaming in some periods but there isn't as consistent as normal poker streamers
You should also check out PokerStrategy's stream - be aware that there even are community streams (Russian, Polish and so on) if you speak one of those languages.
