Jake, I agree with you 100% on the 308 Win. This round is an excellent choice for short, urban situations or long range applications. The correct selection of bullet for each application is the only decision needed. As for the 222 and 5.56 they are quite temperamental when a shot is required through glass or even curtain material. With such a small bullet backed with all that speed, deflection becomes a primary concern, especially in an urban situation.
