I'm assuming you're talking about an endless TR build. It really depends on your playstyle and preferences. I tried using a TR monk but I found it incredibly boring literally using only one skill the whole time. With barb WW is at least more fun because it's more useful DPS wise and it retains useability in higher MPs. Pros of the TR build is that it is extremely fast and a great build for advancing in PLs or farming for gear. Other than that it is really up to you. Personally, I like trying variations on popular builds from the monk, and I've found that I have more funk playing the monk than I do the Barb.
