That's very true, GAN does have very clever marketing, and as long as people keep thinking they're the best, they'll keep selling new cubes even if they are overpriced and underperforming.
Sure, there are some other differences, but nothing very large, and in my opinion not really anything to justify a new name. People get mad about the rs3 m 2021, because it's basically just an rs3 with maglev. That sounds a lot like the difference between the 11 and 12.
Sure, you may like gan cubes, that's fine. But just because some people like them doesn't make them the best or close to it.
Good for you, I hope you enjoy it.
