I'm really just getting into cubing, averaging just under a minute.
I started with a GAN I got as a gift. On the tightest settings, the GAN I have feels squishy so I wanted something tighter. Bought the Tornado V4, and it's my favorite. I haven't made any adjustments yet, just added a few drops of lube. It's got a tighter feel, it's heavier, but still moves quickly. This is kind of silly, but one of my favorite things is that it has a really nice sound as the turns slot into place.
It's just a very satisfying cube.
