3 major flaws of Cherry G3800.
1. The board had no anti slip mat under it, make it (super) easy to slide around.
2. Flat keycaps are completely not comfortable to type on (the edgy feel and small surface area), worsen by the non-standard Caps Lock making it completely incompatible to 95% of aftermart keycaps out there.
3. Under the bottom left part (Ctrl key) there actually a little hollow, resulting a strange and hollow sound when you pressed on the left Ctrl.
I guess the 1st and 3rd problem are somehow solved a little in G3850, but the 2nd point itself is more than enough to be a deal breaker.
