One worthwhile question is do you really need the "best"? Are you running a commercial repair business or a bike shop? Will it be used every day for a wide variety of bikes? Are portability or ease of storage considerations or do you have a dedicated workshop where it can be left set up permanently?

As to the best brands, I consider Park and Feedback Sports to be the two that qualify and they both make a variety of models in a range of versatility and prices. Buy a good and suitable stand but don't overbuy.
