A Sig is a lot like a BMW. Expensive, but very nice and totally worth the price.
It is among what I consider the big 3 brands of production auto's where you can count on out of the box reliability based only on their brand. The other 2 are Glock and HK. Sig also tends to be very accurate.
I carry Sig, and I don't really want anything else. Aside from another Sig when I have the money to spend on it.
No gun is perfect for everyone, so try shooting it before you buy, but I'd say the odd's are very good you'll like Sigs.
