This is quite the conversation! Clearly what I should do is buy the new Grand Prix 4000 S IIs in 28C, which will save weight over my current 23Cs, drastically improve ride quality and reduce rolling resistance, and hope that they hold together when the road turns rotten.
Or I get the Grand Prix 4-Seasons after all, noting that they have double Vectran breakers and Duraskin for the sidewalls, and take comfort in the fact that they are 330TPI tires instead of the 180 offered by the Gator Hardshells, even if they're not the so-called BlackChili compound.
I think the GP 4 Season is an answer in search of a question. They don't ride as nice as the GP4000 S, don't have the long tread life of a Gatorskin, and don't ride appreciably better than a Gatorskin.
While they have measurably better wet traction the other tires are usually fine and none are going to save you if you get silly with leaves, painted lines, or manhole covers.
I'd try a GP4000 S II or GP4000 S 25mm wide if you can't wait
