Aren't North American suburbs generally more spread out than Europe and wlsewhere? At least that is what I have read quite a bit during discussions about urban sprawl. Our cheap gas, culture, space, and lack of a direct impact of WWII led to a lot of suburbs that are significantly less dense then Europe?
Overall, I doubt it would be much different than fighting in a small village or such and would really depend on the forces involved and the specific situation (it may be simpler to just plaster it with shells than to fight for it, or if there is a city providing a better advantage, just a minor rear-guard action and fighting withdrawal).
