I suggest you a little sample pack composed of Treet Platinum, Shark Chrome, Super Max Diamond Edge, Bic Astor, Personna Israeli Red (two blades each). Tryablade and Razorbladesclub are your friends.
The most aggressive shave of all is the naked, unprotected edge of a traditional straight razor or shavette.
Very often people find an ultra-sharp half-DE blade in a shavette quite daunting. Many straight-razor shavers don't hone their edges anywhere near that standard. A blade which is too sharp is very unforgiving. It's much easier to shave with a milder edge.
Check out this razor sharpness guide to get some ideas for blades to try. The best options are probably the ones which are most consistent. Some can vary quite dramatically between shaves.
For example these will cover a range from mild to sharp: Derby Extra, Astra Superior Platinum, Astra Super Stainless, Nacet.
Reporting back: first 2 shaves were with Feather blades and they tore me up. Used a Nacet blade yesterday and it was a 2 pass BBS, no irritations shave.
I think it depends on the razor. I find Nacet, Polsilver and BIC to work great in my FOCS and Fatip OC, but then again these two razors are not very aggressive at least to me but they are very efficient and smooth.
