mp5s are all about picking the one with the issues you feel you can deal with imo. Unless you want to wait and see what LCT's offering will be. We know stamped/welded steel upper for sure, but how the rest plays out is unknown.

The G&Gs that I've worked on have the top 3 or 4mm of the gearbox cut off to make it fit in the uppers. Meaning if you crack the shitty g&g v2, you have to order a replacement from g&g or cut your own to fit. The toptech gearbox is a pain in the ass to take apart and put back together and is also made of the same soda cracker mix of material that will crack if you look at it in the cold.

Anything using the TM design will have the stupid lever hop arm adjuster, TM, ics, and I think JG.

CA and cyma has a slider hopup, CA gearbox specs and part specs have always been a bit suspect, it could take a while to get working right if you want to upgrade it. The v2 gearbox bushing holes I've heard are drilled in offspec locations that are not seigetek friendly, but that could've been years ago or a bad batch or it could be the truth. CYMAs are heavy.

SRC has a stamped steel upper but it's SRC. I have not handled one but it has the nicest upper, probably the shittiest internals by reputation alone.

MP5Ks use a v3 gearbox have very little battery space and their hopup can only be adjusted by taking the foregrip off.. and it also has a reputation of not staying where you adjust it.

CYMA is heavy.

VFCs have a mechanical burst, not sure if you can put a spectre in it or not.

I dunno, if you must have one before LCT comes out with theirs, I'd be sitting on my ics and pick up a CA a4 navy to compare side by side. I had no issues upgrading 2 different CA g36s to use 13:1s reliably but they are v3s and I haven't tried putting seigeteks into my g36, but again it's a v3 so their manufacturing jigs for drilling the bushing holes might be different for v2s vs 3s.

Nobody has come to me looking for a pinnacle upgrade mp5, so my spectre 13:1 build is the furthest I've ever taken one. Most people that come to me want basic or 13:1 builds on m4s or AKs. I've done maybe 5 siegetek builds but all have been in m4s or a test mule v3 I have that I was testing a chimera on.
