As I said previously in this thread, the ELRS receivers suffer from full throttle runaway failures under abnormal (but likely enough to be a concern) electrical faults. Even cheap junk radios I tested did not exhibit the same full throttle runaway problems.

The pwm range when operating in the ELRS 1000Hz mode is not as wide as other radios. One thing I noticed going from my NB4 to the MT12 is I could not achieve the same steering endpoints on my 2wd buggy with the MT12 where I had travel to spare with the NB4. I brought this up as an issue on the ELRS github and got dismissed because basically "that's just the way it is, it's not supposed to be able to do that. go to a slower response rate if you want the extended limits."

And that brings me to my last frustration - it's not one product controlled by one entity. It's 3 products controlled by 3 different entities who will just point fingers at each other when something goes wrong and results in a hodge podge experience as you learn the ins and outs of 3 different systems. This is the most notable when you need to update ELRS firmwares. With my NB4, I could flash receivers or just change settings from my transmitter. EdgeTX is nowhere near integrated enough with ELRS to do that, and I suspect ELRS isn't capable of doing that anyway.

I have yet to find anything I can do with the "infinitely programmable" EdgeTX software that makes its complexity worth using over a simpler, more intuitive/familiar radio like the NB4 I used to have, and I don't need the uber extended range of ELRS (99% of surface users never will). While the latency/response is top notch, the rest of the issues I outlined really have me thinking I should sell my MT12 and get an NB4+. And ultimately that would be my advice to anyone considering this radio - look elsewhere (but as others said, not spektrum lol). Only consider this radio if your budget is limited and your tolerance for frustration is high.
