So, I've been having a bit of a shave-off amongst all the blades in my stash, and it's come down to these two, at least for the time being. Using each blade, I shaved with the same razor (Merkur 25C open-comb), same products (Proraso and ToBS Avacado, at least a shave each), same prep (shave after shower, wet face).
The Feather - very close, marginally sharper, but the Personna MP performed very similarly and was ever so slightly smoother in this particular razor (substantial blade exposure). The Feather gave the closest single WTG pass I've ever had, but the med/lab blade catches up quickly on the 2nd pass. The O-Rub splash is the final arbiter - no burn whatsoever after the Personna shave, and a consistent slight alcohol tingle after the Feather.
The bake-off will continue with my other razors, dialing in the "best" blade for each - what's good for the Merkur OC may not be perfect for say, a Gillette Slim. However, given their similar performance, the MP's slightly higher comfort level, and the MP's price of nearly a 1/3 of the Feather in bulk, the MP emerges as champion from this round.
