They ARE apples and oranges...I have an HS-2000, 2 friends have the XD-40 based on shooting my HS. They're great pistols, always go bang, and for the money, they're STILL a great value...Quantico Arms sells 'em for $389 at shows around here.
The 1911 is certainly a different animal...I don't own one, but I had a friend's for about a year, and shot it a lot. The slide was kinda loose, and it shot about 10' to the left...no joke. I've been after him for years to give me the damn thing to refurbish it, but he just won't do anything with it.
I'd go with the XD, based on ergonomics alone. Small hands, the XD fits 'em better. If you scope on HS2000 talk, someone there is selling a new guide rod that allows you to use any Wolff springs you want, so you can tailor the gun to your personal preference, load, etc.
Just my .02, take it for what it's worth.
