Among all of them, I would say I'm most guilty of pride. Im not really horrible about it, and I'm not really braggart per se, but I do tend to be overtly proud of my skills and accomplishments, even if its in my own head.
As for the others:
Lust: I'm pretty much not interested in sexual stuff.
Envy: aside from a very few cases, I don't care about other people stuff. I've got money, I can buy it myself.
Gluttony: don't eat a lot at all.
Wrath: I sometimes do get mad, but overall I'm a very peaceful person
Sloth: Not lazy whatsoever
Oh, and you forgot number 7: greed: I'm frugal with my money, but am very generous if someone is in need.
So, judging by my answers to the other options, definitely pride
