so, i can help "a little". I have a V9PKX-A-S (that nomenclature means its a commander size, ported, with a full size aggressive steel grip). And I own all of the comparable guns you mentioned.
I say only a little because recent shoulder surgery has me laid up and unable to shoot the gun. So I can only share bench-top review type comments.
And, in that regard, I will say I was pleasantly surprised at the build quality in every regard. The fitment is perfect, tight and smooth. The finish quality (DLC in my case) is top rate. The trigger is basically Atlas quality. The controls are crisp. Zero complaints or even niggles about the benchtop quality of the gun. It compares favorably to the best guns in my collection. The gun is built like a tank.
Wrt to shootability, all I can do is point you to reports from those that have them. There are plenty of reports and actual video's of guys shooting the guns very, very well on their discord channel. Interestingly the folks that have them and shoot them think of them (and use them) as fast, competition style guns. I point that out because some of the earlier reviews here labeled the guns as more of a duty style. Fwiw, I don't find them to be duty style guns. They are set-up to run fast, they remind me of Atlas more than any other builder.
So, overall, fwiw, I'm a fan and Fowler is on my short list of 2011's that I am currently still adding at this point. (the other names that are on my "currently adding" list are Infinity, Venom Custom, Atlas and now Fowler - so I hold them in high regard. There are other names on my overall favorites list; Hayes and Chambers to name a couple, but I have the guns I want from them already.).
