As a guy I would bring my own beer because even if it was enough it wouldn't be the right kind unless the host and I shared tastes.
And a bottle of liquor because I couldn’t bring a lot of beer without intimating my mistrust of the host by bringing my own beer in the first place.
Edit: Also, if I was going somewhere I'd offer to bring all of the beer, and include a wide range and enough of what I like for everyone to leave satisfied.
And some liquor.
Bacchus is lord.
