For now I like the plastic pedals with plastic pegs. Grippy enough for my slick-soled street shoes without discomfort wearing my thin-soled lace up moccasins. Fine in dry and rain. The couple of times I've ridden in mud these pedals weren't very grippy with my hiking shoes, so metal with pegs might be better for those conditions.

But this is for my comfy/hybrid do everything bike. If -- or when -- I get a second bike it'll be primarily for longer and/or faster rides and I'll probably go with metal pedals and those replaceable pegs, since I probably won't be wearing thin-soled shoes with that hypothetical bike. Might even consider the combo clipless pedals.
