Mountain Buggy Urban Double vs. Valco Runabout Trimode Twin?

[CaydenGrace]

I've seen these strollers mentioned on almost every message board. What's it the real deal on these strollers? What about the Mountain Buggy Urban Douible or Valco twin attracts buyers?

I'm starting to think that maybe I should nix my other options for one of these highly recommended strollers.
