The reason i was reffering to the allies as better here is because of
A) - US Vehicle crews with crit repair
B) - Self repair on some light vehicles, (T70 and Bren carrier)
C) - Lots of doctrinal auto repairs on the sov and Brit factions. (especially the brits with the smoke shield)
D) - The allies have combat repair options, the axis you have to run the tank back to base or risk your pio's being 1 shot by some artillery or attacking tank, where as the allies can in most cases stay near the front and not surrender ground, so while the hps of the repairs may not be as good as sturms, tactically and strategically, they are better.
Most things here are not quite right.
A) Crit repair does not repair a tank and is thereby not part of the discussion surrounding repair options/speed. It is however an entirely different problem which should have been addressed a long time ago either by removal or a price increase. The only thing that can be considered correct here is that USF might actually repair a medium tank faster since they do have the vehicle crew to do so and do not rely on a builder unit.
B) The point was regarding repair options for tanks. While again the t70 is problematic in its own right, it is not part of the argument. The bren carrier can as well not be used to enforce your point as it crutches on that ability since there is no repair available until the faction techs up.
C) There is one such option for each of those factions. For the brits it is part of 3 out of 8 commanders. For Soviets it is part of 3 out of 21 commanders. Both abilities render the tank combat ineffective and immobile which is why repair at the front is sorely ill-advised. Even more so with the Soviet ability since it does not conceal the tank as well.
D) Brist and Sovs have the same stock ability to repair in combat as Ostheer does and the same risks associated with it. The only differences are the ones covered in C) which are doctrinal. To take these into account has again got nothing to do with your inital point as it is akin claiming that Ostheer would have better ways to save their tanks with panzer technician.
The two exceptions are OKW (truck repair and increased repair speed with sweeper upgrade and better builders) and USF (vehicle crews).
