Roll is easier and I think less cutthroat. The dice really are fun to manipulate. I don’t know the tiles nearly well enough to build toward scoring solutions the way I can in Race (because I know Race so well) so it mostly feels opportunistic. It’s probably more “fun” to roll dice, honestly. And for whatever reason I never feel completely screwed by bad rolls the way I can feel with bad draws. Otoh I’m not sure how much skill I can actually develop, either.
