(Flagship edition by the way, no setup, straight out of the box.)
X-Man Design absolutely cooked with this one. It's sort of like extreme control and extreme freedom at the same time, in part because of the stability. Normal corner cut goes to slightly less than 45 and reverse corner cut goes to nearly half that, so I wouldn't recommend being solely dependent on the cube for accuracy. Less dry and sandy out of the box than the TV3.
The cube is slightly lubed to start with, but you would need to do some turning to notice it. It is also a bit less tactile, and I heard that there are fewer individual pieces of the cube so it's more fused together, probably helping with the sound and feel. The "ownership card" is perfectly neat and simple. The box the cube is in is a little tricky, I didn't realize at first that the magnets that held it closed were just a little strong. The bag is nicer than the one from a TV3 box. There are beginner instructions for the Roux and CFOP methods, and I find that very cool. By the way, this is comparing the pioneer TV3 and the flagship TV4, and even then, it is straight up a massive upgrade.
