I think the best one is the one you can afford, and like the design features of. I would love a TW-90 with all the bells and whistles, but my budget has me on a GIB with a multi platen. Don't get me wrong I love my GIB, but the thought of having a surface grinder and horizontal grinder all in one would bee the bees knees. You never know after I can afford a milling machine maybe I will be able to come up with a surface grinder attachment for the GIB.
If you are playing life on easy, you are never going to win when it counts
