Looks like you already got the XXX4s, so here is my recommendation: put the Conti GP5000 Tubeless, either 25c (more aero) or 28c (more comfort) on them with either Orange or Stan's sealant. These rims are tubeless ready with tapes already installed in them. You will be instantly faster, no joke, and have less punctures (or at least can ride home when you do) than the Gatorskins. Schwalbe Pro Ones are good tubeless tires also with good rolling resistance (faster) but a bit heavier than the Conti.
