This comparison does not make any sense.
Of course it makes sense, CoH2 back then had so many fucking major issues that it was an absolute dealbreaker and made 75% of the playerbase quit in 3 months. If the launch is terrible, then the entire game's future leaves little room for hope.
While CoH3 in it's current state is far from perfect, there isnt really any dealbreakers that make the game unplayable like it was the case with CoH2.
"Cartoony graphics", a couple missing QoL features and weird audio etc. is all annoying, but it won't make people stop playing... apart from the people who would have quit the game after <100h no matter what. Hell, the balance craziness on both sides can even be fun af for the average player.
Considering Relic prioritized SP for launch (SP is way more important for sales/money than MP at the beginning; that's just a fact) I would say we can be pretty happy, this is the best multiplayer launch experience in CoH history.
The game runs smooth even on toasters, there is no unplayable lag, there's already 4 factions, and with the ladders there is even something to grind for already.... none of this was the case in 2013.
Yes, after 8 years of patches, CoH2 is more polished and superior in some aspects than a brand new title from a medium sized company, holy shit. But that doesnt matter when a lot of people are bored to death by the previous game by now... which they are as long as the new game is overall in a decent okay spot, which it is
