The complaints Ive heard is that its loud suppressed for a pistol caliber gun
The jury simply isn't out on the MPX yet, and Sig keeps revising the design despite its short life from my understanding. While improvements are always welcomed I know there is some parts commonality issues between the generations of the MPX, which is pretty annoying IMHO.
Maybe one day a subgun will outperform the MP5 series, but I dont think its going to be the MPX
It's a shame HK got so committed to the UMP design, a MP5/45 would have been the only dramatic improvement in the MP5 series and would have had broader appeal than the MP5/10 and MP5/40. Failing that, they should have retained the roller lock style bolt in the UMP because it's a clunky blowback and the polymer design wasn't a dramatic weight change. I also think the MP5 has a far superior suppressor mount than the UMP.
Really the only thing the UMP brought as a dramatic improvement was mounting optics and HK could have easily borrowed the SIG solution from the 550 series.
It's hard to be a ACLU hating, philosophically Libertarian, socially liberal, fiscally conservative, scientifically grounded, agnostic, porn admiring gun owner who believes in self determination.

We didn't notice a difference with subs, but that was out in the open in the desert... which can be way different than in structures, etc.
I'm not sure what the performance needs/requirements are. But to ME.... sub guns are just for funzies. No way in hell is it a real world fighting option. Durability is always a plus to me. So if the MPX fell apart down the road, that would suck. But for simple steel banging... the sample I shot is pretty good.Maybe one day a subgun will outperform the MP5 series, but I dont think its going to be the MPX

Why even consider the MPX when the B&T APC9 Pro is available. The MP5 is the gold standard, the one to beat. IMO the APC9 Pro beats it. And I say that as a lover of the MP5. Where the MP5 truly has the most merit as a civilian is in its ability to be a sear host and live up to its full potential as a SMG. The MPX suffers from the fact that SigSauer USA makes it. Had it been made by HK, SwissArms, KAC, LMT, B&T, or really any other reputable manufacturer that values QC/QA, it may have been a great implementation of an interesting design. Instead it’s been beta tested by its early adopters. Hard pass.

For me, the interest in PCCs is cheap hearing-safe shooting. On an outdoor range with no overhead cover, I can shoot my suppressed MKE MP5 for hours without earpro with some coated lead reloads. That's the problem I have with otherwise nice PCCs using blowback operation like the B&Ts: loud noise from the ejection port when shooting suppressed. IIRC, the suppressed blowback guns I see sound tested all test over 140 dB at the ear. If B&T designs something with a locked breach or delayed blowback and faster controls, I'll be interested.
I own a couple fullauto MP5s and have shot the fullauto APC9 side by side with my MP5K-N suppressed in an indoor range without ear pro using 158gr Fiocchi subs (my preferred subsonic loaf across all suppressed 9mm firearms). We did not meter, however subjectively the APC was no louder than my MP5K-N. The ejection port noise was not uncomfortable either.
Re: controls, the APC controls are very ergonomic, even more so on the Pro, and far more so than the MP5. I’m not sure how you could make the APC9 Pro controls any faster. This is not a knock on the MP5, as they are truly my favorite Subguns in my collection.
The hydraulic buffer in the APC makes for a smooth shooting subgun/pcc.
