I've had most vintage and modern adjustables, The Futur, a Progress, Slims in all flavors, Fatboys, Toggle, Gibbs Adjustable, Etc... I think the only ones I've not had are the executive and the 195..(and the chrome Toggle)
My verdict..
In the modern camp, Progress, because the Future and I never got along, and boy did I try with that one. The Progress I have is pretty banged up. (cracked handle & all), but stil an ok razor when I find it again.... (it's in a box somewhere I think...)
In the vintage camp, it's a bit harder, I'm no fan of the Fatboy myself, it just doesn't cut the mustard, and I've tried about 10 different ones to make sure..
The Gibbs is lovely, but just not practical as you need to mess with the blades to make them fit, but it's a lovely shaver.
Looks wise & technically, I love the Toggle, but it's just not that brilliant, not worth the money, unless you're really into collecting
Then there are the slims, I love the short handle superslim, it just feels right, that and the standard slim are my fav.
Here is a pic of some of the adjustables Gillette made:
