I guess this is a classic example of YMMV. The Personnas work fine for me in most razors, including the PAL Adjustable and Injecto-Matic. I don't find a great deal of difference between them and the Chicks.
Yeah we're all different....different skin toughness and texture, thickness of beard, shaving techniques.....etc.
There's people who really like the Feather SEs and come to their defense but personally they just don't work for me. I also prefer the modified Gem blades in the early Valets anyday.
Basically the same issue with the Personnas in the injectors. I might get a decent shave or two in certain razors, but then they give pretty mediocre results at best. Much like the Gem SS blades in the Valets, the Chick always seem to give a better shave in the injectors I've tried.
But as you say YMMV
However, lately I've been using NOS blades and the Japanese twin blades, which blow them both away.
I used a NOS Twin in my L [meant to say L not M in my other post and my edit time was up]. Loved it, one of my best shaving experiences ever!
I have some NOS Plus Platinums I've been wanting to try. Any opinion on those and advice on the best razor for them?
