Which is better, self-grounding or 2 wire clearance markers?

I'm looking to replace all of my clearance lights on a 77 Minnie Winnie. I've noticed that some are two wire and others are one, some are normal bulbs and others are VIBAR(tm). Does anyone have any opinions on which are better? My old ones were a two wire system, but one was replaced at some point in the past with a single wire one. Any preference to brands: Bargman, PM?

The 1 wire lights are using a mounting screw as the ground. This is good until it starts to corrode. I prefer the two wire system. With a real ground the light will work as long as it has power and a good bulb.
