The big difference in the Grand Power is the rotating barrel locking system.
The concept of rotating barrel locking was originally patented, i believe, by JMB himself in 1897. However, early implementations were finicky and reliability depended on lots of good lubricant. More recent designs that use this system include the Beretta Px4 Storm and the Boberg XR9.
GP Designer Jaroslav Kuracina has a fresh look at the concept and controls the barrel rotation with a large, wide cam surface in the barrel interfacing with the top of the slide stop pin. Other designs have typically used some kind of pin or post running in a groove milled in the barrel. The GP's larger engagement area spreads the friction out in a way that positively impacts reliability.
Rotating barrel designs typically take more energy and longer unlock time than a tilt link system, while at the same time traveling less distance to the rear. This reduces felt recoil and allows the designer more room in the action, or a shorter action (See the Boberg).
Additionally, the GP40-10mm has a interesting take on the thumb safety that I think I like. Up is safe and supports condition 1 carry. Middle is off safe and traditional SA fire, or DA/SA if the hammer is down for the first shot. De-cocking is possible by sweeping the safety lever down, and the lever can be left down making the gun operate DAO. As far as I know this is the only gun that allows this DAO operation mode in conjunction with condition 2 and condition 1 carry.
Shooters of the P40-10mm suggest that felt recoil is more in line with a 9mm shooting +p ammo.
The Grand Power designs have been badged by STI in the past as the GP5 and GP6. I am not sure what lead to STI moving away from Grand Power.
The Glock vs XD is an old debate, and IMHO there is no compelling reason for someone invested in the Glock eco-system to look to the XDm. I have an XD in my safe in 9mm and it is a great gun. But before he arrival of the XDM 10mm, like you, I have a Glock 20 SF and a Glock 29, along with 9X25 barrels for both of them, and 15-20 magazines, including 4 that are altered to use the KRISS mag extensions making them 33 round mags. Fully loaded out I think I could shoot 300+ rounds from my G29 before I had to re-stuff a magazine.
If I were shopping today for a polymer full size striker fired handgun as my only 10mm gun, I would very likely end up with the 4.5" XDm.
The Grand Power is the gun I would be most inclined to take a chance on right now. I have been shopping them on Gunbroker and trying to decide how to break the news to my SO.

OP, it would be nice to give a heads up when you make a major edit to your original post and title. Now that I see it is TNW and not PNW as was originally posted, it is much easier to determine what your are referencing:

I don't have one and probably won't buy one, so I can't really speak to them.

I have a TNW Aero Survival Pistol which I bought a stock and 16" carbine barrel to put on it. I'm in the process of trying different loads to see what shoots most accurately.
In the pistol configuration, it likes 200gr bullets the best. I'm getting groups of about 6" at 100yards. I hope the carbine barrel turns out to be as good, or better.
