Wait, just to clarify. MMD isn't very good specifically if you're making porn. If you want to do SFW stuff then yes MMD is easier than Koikatsu because the porny aspects of Koikatsu's engine will interfere with attempts to use it for SFW if you have any ambitions greater than still images.

It's also only better if you have actually good cards to work with, but considering Hololive is super mainstream I'd be willing to bet every single one has a very easy to find high quality card out there.
