Sig. Is it better? Not really, very subjective and relative to the user. Handle both, and decide based on what you're comfortable with. Better yet, go to a range that rents both and shoot both of them. You may find that this answers your question. I can't get used to the grip angle of the glock, to me it feels like I'm holding a 2"x4" out in front of me at an awkward angle. Thats one reason I got a Sig(P229R). Aftermarket is great for both, but you can customize a Sig easier than a Glock. So my vote is Sig. Not because it's better, it's just better for me.
