I like both, personally, but I am along the lines of "would never trade a Sig for an XD." To be honest, it is a matter of prefrance. There isn't much there to compare between the two as far as look, feel, etc. Two completely different guns. I think both are very accurate. Haven't heard a lot of complaints on either one. So that is a tough call. Have you shot an XD yet? I would most definetly shoot one before you go through with this.
