For me
Most fun:PRX super aggressive play style
Most boring:hard to decide but probably Guild because of their slow and patient play-style and not really having a big star player
Most fun: PRX, DRX (its one of the only teams, that is also fun to watch when they lose, cause it takes a masterclass performance from the enemy to destroy them), Fnatic
Most boring: Lulquid (by far the most overrated and boring team ever, I only respect them because they knocked out two NA teams in champs)

The comentators were talking about how Guild had such a good read and everything.
They sat in spawn, waited, pushed, ran away if they saw a single soul, repeated every round on fracture. I was watching just yelling
"HOLY SHIT, THESE GUYS ARE SO FUCKING LAME"
They were so fucking lame. You have sayf and trexx. Run at F0rsaken and if you kill him you deserve the round. If you don't kill him, you're shit and should FF now.
PRX never back down though. Run and kill em. Best team to watch.
Edit : Fnatic is also fun to watch. They are calculated, like Guild, but how they use their play and molding of the map is much more efficient and exciting to watch. Guild relies on the other team giving up space (by rotating because they're so bored) to gain space, while Fnatic pressure and mold the map around to where they want to hit.
