Completely agree with this statement, and others that sound similar - it's personal preference. I loved my XD's. Probably still would if I hadn't swapped them all out for XDm's, which I personally like better - notice it's just my personal opinion. Others have differing opinions.
Here is my take, which I wrote separately to cut and paste here after I saw your question earlier:
You are comparing entire families of pistols to each other. What exactly do you want a comparison of? There isn't an exact cross match in each family. For instance, in the XD family of pistols, you have the following:
XD Sub-Compact 3" in 9mm and .40
XD Service 4" in 9mm, .357 Sig, .40 and .45 ACP and GAP
XD Tactical 5" in 9mm, .357 Sig, .40 and .45 ACP and GAP
Then you also have :
XD Compact, which is a .45 ACP with a 4" or 5" barrel, but shortened grip
XD 45 ACP section, which lists other .45 ACP XD's, but highlights the 14 rounder.
Moving over to the XDm models, you can see a difference:
XDm 9mm, .40, .45 ACP in 4.5" barrel, full size grip
XDm 9mm and .40 in 3.8" barrel, full size grip
XDm 9mm, .40 and .45 ACP in 3.8" barrel, compact size grip (about like the subcompact XD length grip)
XDm 9mm, .40, and .45 ACP in 5.25" barrel, comp series
Note a few differences right off the bat:
1) No same size barrels to compare in the XD to XDm series. XD's have 3,4,5, and the XDm's have 3.8", 4.5" and 5.25". Think they don't make any difference? Some say yes, some say it's all in your imagination.
From personal experience I believe that the XDm Compact (3.8" barrel) has less muzzle jump, and is an easier weapon to handle and get back on target after each shot than the XD Subcompact - both in .40. I owned the XD-40 subcompact, and I now own the XDm-40 compact. The subcompact was a great little gun to shoot, and I really enjoyed it. However, I found it to be a very "snappy" weapon. I was just about to replace the barrel in it with a 4" ported barrel from EFK Firedragon, which I had been waiting on a LONG time to be released, when the XDm-40 compact caught my eye. Instead of buying a new barrel for my subbie, I just replaced it with the XDm compact, and I'm very happy with the results. It's still "snappy", but I find it easier to handle than the subbie.
The second weapons that I compared are my former XD-40 Tactical versus my newer XDm-40 4.5" full size. Both are fine weapons. However, due to accuracy in my Tactical (a problem several people I had shoot it commented on), I had replaced the XD barrel with a 6" EFK ported model in the XD. It was a great weapon, and fun to shoot. But the deciding factors - accuracy without having to use a huge barrel that extended from the front of the weapon by 1" with the ports. The EFK barrel was more accurate than the factory barrel, but I didn't care for the factory. I almost sold the ported barrel to replace it with a match barrel from either EFK or another manufacturer. The XDm was accurate right out of the box, and only getting better with time.
2) Magazine capacities - pretty different on the 9mm and .40 models. XDm's simply hold more - unless you are in California. .45's use the same magazines - XD or XDm. Pretty nice.
3) Changeable backstraps to adjust the grip feel on the XDm - not available on the XD.
4) You don't have to pull the trigger when disassembling the XDm. To disassemble the XD, you lock the slide back, push the slide disassembly lever up, release the slide, pull the trigger, and pull the slide off. On the XDm, it's the same minus pulling the trigger.
5) Grip safety and grip angle, USA Trigger system, striker status and loaded chamber indicators are basically the same on both XDm and XD's. The XDm is supposed to have a better trigger with shorter reset. I can't really tell much of a difference, but I do know that the XDm triggers seemed to "break in" much faster than their XD counterparts in my comparisons.
6) No .357 Sig or .45 GAP models in XDm family.
Oh yeah... the XDm has that little "m" at the end.
Hope this helps.
All the best,
