Honestly, I never thought there is a cube as good as the GAN 356 XS.
But this one is.
Feels somehow like a mix between X and XS : Crispier, not as buttery, but faster than X, less crispy and heavier than XS.
As written in my XS Review : I sold all other wannabe mains (including MoYu & QiYi / Valk) and have the XS now several times (Standard / Angstrom / Cubicle Custom).
I bought this one here (X V2 2020) only because the X was way ahead of its time. Definitely not only way better than expected, but the only true competitor to the new flagship XS.
I don’t want to (endless) discuss about customisation and other technical differences between the two. Just one hint : They are both out of this world, even ootb. One is light as a feather (XS), the other slightly heavier but a little faster.
Let your preference decide.
And, don’t get confused by negative reviews : Most of them are written by those who never buy an expensive cube or MoYu hardcore fans.
Want me to tell something to those MoYu infected ? I had 54 MoYu cubes over the years. ALL OF THEM CAME WITH SQUEAKY NOISES FROM THE SPRINGS (as most Valk / QiYi). Are you serious ? Spending 50 bucks on average an then you have to dismount and grease the screws and springs ? Well, you can keep on doing that and pretend your favourite brand is the best.
Or, open your eyes and your mind - it’s simply impossible not to appreciate this level of perfection !!!
