1. Gillette Silver Blue
2. Voshkod
3. Personna Med Prep / Super
However, just to complicate matters, some blades work well in some razors but not in others. Sputniks are fine in a Merkur Progress but not in any other DE I've tried. Silver Blues are a bit much in a R41, but Permasharps are great in that razor but lacking in my Weber.
It's all VERY personal and you'll only know but your own trial and error. I actually keep a couple of blades I don't like and try them in new razors: Kai and Feathers are great in a 37c but hateful in all the other razor I've used them in ...
