I watch both, and they definitely have different things going for them. I think something that is missed in appreciation of pro play is just how smoothly coordinated the players are. They make it look effortless, the same way high APM Starcraft2 players make things like fighting on multiple fronts while managing their macro look effortless. It can be really noticeable when a player gets swapped in the middle of a tournament run and the team doesn't quite gel back together right away.
