TK3 does not have brakes, so you might consider that when comparing costs. I personally like the TK2 better, but it comes at a price.
I have a curbside which is the same as the dispatch except bars and color. I like it a lot but not everyone is a fan of that geometry. My MTB has a horizontal TT and my road bike doesn't.
It all comes down to personal preference and how much you want to spend. Ride both and see which one gives you the biggest thrill.
