This. Anytime somebody lists 4e's limited range of effective game styles as a flaw, they're missing the point. It's better for your system to do a few things really well than for your system to be mediocre at a lot of different things.
I agree with your comment - 4e does a limited range of things very well. However, expand out to the OP's question if that limits different types of play styles. It does.
Just because Chess is a great game doesn't mean that I can't enjoy Settlers of Catan. Just because 4e is great at what it does doesn't mean that it does everything for everyone. That doesn't reduce 4e as a game.
