Disappointment is probably a better gauge for how bad a cube is. You aren't buying a Rubik's brand expecting it to be revolutionary, and of course its objectively bad but at least you expect that. The Dianma is up there, especially since it was produced right after Moyu pumped out a bunch of hard hitters like the Weilongs. However, I think that the GAN cubes between the 354 and 11 are by far the most disappointing. I really thought that GAN was a great company up until the X came out. I thought it was alright but from what I tried it wasn't any different from my 354. That was December for 2018. It took Gan 2 YEARS to get something to the table that had some actual innovation that wasn't the same product with moyu "inspired" hardware. However, the 11 restored the smallest bit of faith that they would actually start trying instead of just copy-pasting cubes, then rolling a dice to decide what the price would be. The cubes themselves are still fantastic puzzles, I even got a 356 M for my little brother for Christmas (despite my moral compass dragging me away from it), but they are far from the revolutionary hardware GAN was coming up with back in the days of the Air series.
