Have a City Select and absolutely love it for all-around urban and off-road use. It's not good on public transportation where the stroller must be folded, however. because it doesn't really fold--just kind of collapses onto itself.
Also have a Britax B-Agile for use on the bus and to keep in my trunk. It's fine for those purposes, but I don't really like using it for walks because it isn't as good on rough terrain, doesn't fit much in the basket, and isn't great for tall users who take long strides.
