I have run both Grandprix 4 seasons and Gatorskins (but not hardshells). Some people have mentioned them being skittish in the wet, I don't find that. They do take some wearing in but give ample grip. Current set is on 7,000miles. Run them all winter on rural lanes, for commutes and lesuire, through the endless rain, wind and local flooding. No problems. 4season tires give supreme grip, imo at the cost of speed...better suited to cold winters. They are less reliable than the gators puncture wise and for me have a shorter lifespan.
