Buying a non-rubiks brand can be confusing. There are a ton of fantastic cubes out there, but there are also a ton of abysmal ones.
If you're set on a rubiks brand, they DIY's are the way to go. The storeboughts can be very hit & miss with turning quality and you can't adjust them. They DIY cubes (from the store here) are fully adjustable so you don't have that problem.
If non rubiks brand are of interest, the current favourites are the Guhong. I've got one on order.
