But UKF stock tanks (plus Valentine) are absolutely better than most axis vehicles. Churchill has so much health that in order to make sure it can soak damage and come back quickly to the field, UKF has specially designed sappers and every second commander has repair abilities. It is simply much better than what axis have.
You may even have problems to finish off a churchill in smoke repairs (plus engies - why not?) as you have to attack ground with a pak and churchill can still bounce, and often you won't be dealing enough damage to destroy it - it will be repaired faster. It will definitely give time for the UKF player to mop up your at guns. Often even with sappers. Of course if pak/s survied the churchill push in the first place. Lategame UKF is really good.
What tanks would they be? Cromwell could do with a ten fuel increase now MGs are reliable but everything else is roughly in line or worse than their axis counterparts.
Centaurs speed let's it down compared to ostwind despite their dps being almost identical. Pretty important for survivability.
Comet is basically the same power level as panther but trades AT and range for better AI. Well balanced tank finally.
Churchill is currently dead. Thank the big chungus popcap for that.
Rocket artillery to match stuka or werfer doesn't exist
FF is slightly worse than Jackson and SU85. Similar DPS to jagdpanzer vs heavies depending on armor value is slightly worse or better. Much worse vs mediums compared to JP. I would trade it for a Jackson or JP in a heartbeat.
If you made that claim on UKF release OK, but every tank in the UKF roster has been hit pretty hard with the nerfhammer. They're nothing special apart from croc
