I don't know about a best, but I think the most coveted would probably be my Mappin Lancet Edge. Or maybe my DePews that Max restored. Or maybe my 9/8 GB/Anchor. Or... or...

In short, my keepers are what I found to be the most interesting/unique/beautiful razors that I have had come through my hands in the 3 years I've been into straight razors. Well, minus the first few months, during which I let some go that I wish I could get back.
