I like to play both, it depends on my mood and my time for playing.
But I also think, that you have to adopt your game style to the number of people at
the table. If there are less peoply you can play a more loose style and should play more hands, because the blinds are running much more often over you.
With more people you have to stay especially at the beginning more tight in my opinion. But I think, it is nice, if you have the possibility for variations in games.
