Power gamer is a pejorative term for optimizer. The two have the same relationship as prima donna and roleplayer. If you only ever use the pejorative to refer to a group, you're not just judgmental, you're prejudiced.
There are optimizers who calmly go through the numbers, run their character for the good of the group and ask other players at the end of the session, "say, what are you thinking about getting next time you level up Ariana? Oh, OK. Well, I know you want that for concept, but you'll get more use out of this other thing - maybe the ref will let you 're-skin' it?" They're actually more common than the problem optimizers who lord their system mastery over other players. It's just that the prejudiced set of the hobby say things like, "Steve? He's not a power gamer, he's a friend of mine!"
Here's the thing, though: Steve the optimizer is a "power gamer" and a "munchkin" too. And when you use those words that way, you're no friend of his.
