I'm both, although a little bit more powergamish.

If I know there is a battle ahead, first I'll try it in a roleplayer-way. If I don't make it after couple of reloads (someone usually dies simply due my own stupidity [img]smile.gif[/img] ), then I'll take the powergaming-path and prebuff.
And usually I try to stick to the character/class/alignment I have chosen, although I find it somewhat hard doing things in an evil way. I guess I'm just 'too good' person to even roleplay evil.

Or then it might be 'cause I just want high rep and so cheapier prices.
