I think this is going to be your major decision maker. If you like FBV, it makes sense to use the machine that is built by the people who invented the tech. I personally love FBV. First time I tried it, it took getting used to (almost felt slippery), but once you get used to it, it's fantastic and it's the real deal. I once had to go back to ROH for an emergency sharpening at the rink, and my skates felt so "sluggish" compared to FBV. I'll never go back to ROH if I can help it. Both machines are great and both have phenomenal customer service. IMHO, the Wissota has a much steeper learning curve than the X01/X02. However, If you're out playing, and you need an emergency sharpening somewhere else (like I did), chances are you're more likely going to have to get ROH, as it's more common. And in regards to sharpening your own skates... I am very picky. I once had FBV done on my skates, and I kept losing my edge cause they were poorly done. So a lot of the quality is on the operator, more so than on the machine. When I sharpen my own skates, I know #1) that it was done with meticulous care, #2) that the edges are to spec and that they are level, #3) they can be done anytime I'm around my machine (so no waiting, no trying to get to the LHS before they close, etc) When I first got my X01, it took me about a hour to sharpen a pair of skates to the desired level of quality, cause I had to figure this thing out, reposition this thing there, etc, etc... but now I can sharpen my skates with very good precision in about 5 minutes. Plus now I sharpen for my kids, and in no time, the machine should pay for itself pretty quickly. Best of luck in whatever machine you get!
