So they don't have better tanks
Which OKW tank is superior? AEC is better than the luchs, P4 worse than the crushwell, comet is better than the panther, Churchill Croc is better than flame hetzer, Firefly is better than the jp4 ( JP4 does have better vet). So that leaves what, KT and JT (puma if you want to count that as a tank)? In the majority of the cases, OKWs tanks are not better.
shreck + fausts are worse than just Piats?
You mean the single shrek that OKW can get? Shreks on sturms never make that big of an impact.
Id rather an invisible, retreat-able garrison-able AT gun than the 6PDR but that's my preference.
Because you've never used it before and seen how many times it hits fence posts. Plus garrison on it is a noob trap until they fix hold fire and the only reason why retreat is necessary is because it has to get to 30 range to actually hit anything. Better to just have a normal ATgun that can fire from 60 range (from in the FOW) and just reverse if things are getting near.
If you think the rakken is the better than the hyper accurate, hyper mobile 6pdr, you are delusional and willfully ignorant.
