Men take pride in their accomplishments, tools, and toys; so compliment a man on what he's done, the tools he works with, and the toys he plays with.
These claims are not true in every case, but they represent general trends.
Personally, I'd rather receive compliments for my cooking, my test gear, and my RPG materials. When a woman compliments me for my looks, it only makes me suspicious of what she really wants.
