Hi. I got a four type sampler pack, and I'm trying to understand how the blades relate to each other quality-wise. I realize YMMV, but still, which would you consider best, sharpest and smoothest? They are:
1. Gillette Platinum
2. Derby Extra
3. Gillette Silver Blue
4. Gillette 7 o'clock super stainless (green box)
