I voted "other." If you look at my SOS postings, you'll see that I use a Feather ACD-N as my base razor the majority of the time. I mix that up with the occasional str8. My goto razor is a Merkur 34C but I donated that to a worthy cause and rely on the 34G version instead. My normal secondary razor to the Feather ACD-N is a Merkur Progress. That stays in my shave kit all the time while I'll rotate a different DE razor each week into my kit next to it. Now that I have you all confused...
Well, after a few days of trial I can safely state that the Gillette FatBoy is definitely superior to the Futur IMO!
Merkur Progress I have a modified Merkur Progress that is my current fav! It has a metal knob on the end instead of plastic....just love it.
Yes...you really cant go with the 40's..while you may not be as wild as today...they get the job done
I tend to favor the one I'm currently using!! President, #58, #16, Double Ring Rocket, HD and Slant. I tend toward more aggressive, heavy razors. One of these days I may try an adjustable again. Last one I had was back in the late 60's. That said, once you determine your agressiveness preference, I tend to think the blade and soap have a larger impact on shave quality than the actual razor.
I don't buy a lot of razors because if something works I tend to keep it. My vote should really be for "other" for this reason since they all stick around but a three piece is really my favorite, nice and simple.
