I think this vs Bustin' Out comes down to preference over the things each game does better than the other. Bustin' Out better characterizes the player character, Urbz better characterizes the rest of the cast. SimValley is a more interesting setting mechanically, but Miniopolis's New Orleans slant is more interesting aesthetically. Bustin' Out is grounded (insofar as the Sims is ever grounded), Urbz is more out-there. I think I like the overall gameplay loop to Urbz more, much as I feel there's more purpose to Bustin' Out. I prefer the pay-off for certain character arcs in Urbz, as much fun as the characters are in the out-of-context existence in Bustin' Out. But both are good!
