I have been through a bunch of platform pedals - MKS Lambda, VP-001, Raceface Atlas, Straitline Amp, Blackspire.
I'm most impressed with the Atlas and Blackspire, but the Atlas are probably the wrong pedals for a road bike.
I had a click under warranty on the Atlas that proved to be a brinnelled axle. Raceface honored their warranty and sent me the rebuild parts. 8000 mi later they're still going.
I'm sure I've got 5000+ miles on a pair of Blackspire with no worries.

If you check reviews on Blackspire, they seem to be everybody's old reliable.

If you compare width to length, the Blackspire are the most versatile, and you can find them all over for $75 or so.
