I have continental GP 4000 S II on my fast bike and love them
for my daily commuter, I have used different tyres. Gator hardshell are crap in the wet as you slip and slide. Schwalbe Durano Plus are bombproof, and much better than Gators
I'm collecting a new bike for commuting today, and the tyres fitted are Continental 4 seasons,.... I've never tried these, but will use them till they need replacing, and will most probably use Durano plus during winter, then switch to GP 4000 in spring
Mitchelin have a few new tyres that seem pretty good aswell
