As long as the criteria is best shave and not the most cost effective shave, for me it is a Gillette Power Fusion Pro-Glide. Not cost effective because I can only get three shaves from those very costly cartridges.
A close second is the Schick Power Hydro Five. Cartridges are a little less expensive and will go five shaves.
Using one of them once a week makes whatever else I use work better. If I skip a week, the Gillette Sensor really falls off. Otherwise, the Sensor will go five to seven shaves.
Using a Schick Quattro as my daily driver and one of the above mentioned five blade power razors once a week is really the sweet spot though. I can't say enough good things about my Quattro.
