Hilarious tbh, I remember in the homeland when the smug Nijikeks used to compare 3Ds because theirs was obviously much better than Holo's.
Of course what many people neglect to mention is that Niji had been huge since basically their first wave back in 2018 and they had plenty of capital to get better models, the scrappy Hololive didn't get their big break until gen 3 and only became truly powerful in 2020, so the tech took a couple of years to get there.
You can clearly see how the models, both 2D and 3D get noticeably better after a certain point in time, Myth just had the bad luck of having their models made in the old gen era but only being able to use them 2 years later when the company had already moved on.
