I want a P99 compact, so I'd say go for that!
However, remember, for every gun that has a problem there are the vast majority that don't.
I'd go with the P99 compact to gain the advantage of a larger caliber (9 or 40). The PPK is a classic, after you get a P99, maybe you could get a PPK just to say that you have one. Either will serve well, I think.
