Just get the WRM series, they are smaller and way better, here's my experience with them
AoChuang WRM- I tried my friend's aochuang, two solve sin and I almost got my first sub 1 single (1:00.16), It feels way better than the MGC and I would choose it over the MGC.
AoShi WRM- I just got this cube a few days ago, my time dropped from 2:30 to 2:07, which is quite good considering it happened by just switching cubes. I also used Anyu Zhang's Aoshi and got a 2:15 Average, which was very good since my average with the MGC was around 2:30.
AoFu WRM- Definitly get this one. First of all, it' 64.5mm, the mgc is 68mm. It' a big difference and its small size make it very enjoyable to solve. The shades of the Aofu are more vibrant than the Mgc's, and it has an anti-popping mechanism which actually works since I rarely get any pops when solving it, which isn't true for the MGC.
In conclusion, the WRM is currently the best choice as of 2022, it feels more 'premium' than the MGC and It is considerably smaller than the MGC.
