I think it depends on what you’re using it for. If you’re going to a big party I think a better optimized avatar is kinda respectful to the people around you (plus higher likelihood that other people will actually see you). If it’s just you and a few people hanging out though, doesn’t typically matter

Avatar performance ranking for me is more of a guide/suggestion than an absolute, it’s not going to be able to account for certain things that might be more optimized than what it suggests and sometimes ends up being counter intuitive.
