But those are foundries, not specific typefaces. If you're refering to the first s i would name Lineto, Commercial Type and H&FJ.
But this is changing on a weekly basis
Hoefler & Frere-Js - classic beauty
Sudtipos - argentinian creativity
Linotype - a little bit of everything
My favorites are...
2. Helvetica Nueue
3. Myriad Pro Light
Foundries or faces???
ok ok, favorites are
Foundries? Great Lakes Lettering, Flat-It, Sudtipos right now!
2. Supria Sans
As foundries, I'd name:
oops, that's 5... but I really like the originality of the new wave of font designers, rather than the big font corporations
2. Helvetica neue
3. Any retro fonts (such Thirsty Rough by Yellow Design Studios)
Maybe next week I change my top 3 lol
