I have used them both. The NT555 works great as a tire in all weather and temperature, except snow/ice. The NT555s are not very good for corner carving, either.
I wouldn't drive Goodyear Eagle F1 Supercars below 50*F. Seriously, they are that scary.
FWIW, I use NT555s for daily-driver use and some 285 F1s for autocross. The F1 supercars get a bad rap, but they are actually decent for corner-carving if you get heat in them first. They are not drag racing tires; you cannot launch hard in them. I would not use them for daily driving, either.
