I live in California so YMMV depending on the laws where you live and the temperament of drivers.

If I do a "proper" stop at a stop sign (0mph, place foot on ground, fortunately I don't clip in), cars will see me stopping and try to blast thru the stop sign when it isn't their turn. So I end up stopping while the first car goes thru the intersection, and while I'm getting resituated on the pedals a second car enters instead of waiting their turn, making my situation more dangerous.

One nice law we have in California is that the "walk" sign applies to pedestrians and bikes. This gives me a chance to assert myself in the intersection before the car across from me tries to sneak in a left turn. It also protects me from cars trying to turn across the bike lane.
