I have played the DV888 and the 888x.
They’re not very alike, the DV888 feels chunky and bulky, is a little big bigger in width and diameter. I really don’t like the flat rims because they will kill the tilt if you land it there.
The 888x is more fun in my opinion and I like it more because the rims are not flat and have a nice organic rounded shape to them. The 888x captures the essence of the past decade’s yoyos while the DV888 is more like a very basic modern yoyo.
