Platforms for me. I don't want to deal with cycling shoes.

I got some shoes that are kinda knobbly on the bottom, and they got stuck getting in and out of the toe clips, so I removed the toe clips for now. Also, I tend to hop on my bike wearing whatever -- sneakers, sandals, even flip flops if I'm just going down the street to the store during the summer. Platform pedals accommodate all of those things. Sandals and toe clips was do-able, but not entirely comfortable.
