CoH1 vs CoH2 comparisons don't exactly work because coh1 was designed around allies win early axis win late. Allies fought for veterency axis bought their veterency. So late game you would have terminator Grens that even if wiped did nothing to dmg the axis player because they were meant to win at that point. In this case we sort of have role reversal where Volks will be highly vetted before obers come out and obers have to fight for it. Which obers would get help vetting up if the volks were meatshields for the obers to shoot at the opponents vetted squads.
I'm not sure how the latter part dismisses comparisons to CoH1.
CoH's strategic upgrades allowed for multiple distinct playstyles in the game that didn't necessarily guarantee a win for either side at some point in the game, though perhaps one might have an advantage. USF had the option of fielding absurd amounts of infantry late game, or absurd amounts of armor, or an absurd amount of combined arms units.
Wehr could field vet 3 knights cross and other infantry, or push for one of the tiger varients, or even rely on carefully placed 88mms to bleed your opponents of VPs.
CoH2 has very little variation along these lines, with most of the strategic choices boiling down to little more than choosing 3x infantry, or 4x infantry. Heavies or spam mediums.
All match-ups boil down to allies having ultimate infantry supremacy, and axis having ultimate vehicle supremacy in the late game. There's no war machine to give USF armor supremacy, and there's no vet 3 KCH to give axis infantry supremacy.
