All of the above. Platforms on city bike (Globe Daily), Eggbeaters on the commuter (Kona Dew Drop) and platforms with powerstraps on the winter-commuter (Marin Nail Trail). If you want to ride clipless in a city environment with lots of stop and go, the Eggbeaters are nice since you can engage from all four sides. I can engage the Eggbeaters on the first try 95% of the time. I don't think there is a wrong answer, it's what works for you.
