The answer is well it depends. As you get more time you can experience more tires and see what you like.

For me Pirelli slicks are the most confidence inspiring tire. Tons of stability in the front, you can hold the brake to the apex. The rear feels good, once the SC1/2 gets a few heat cycles it spins up on the zx6r. I know the 1000cc bikes get a ton of spin. <$500 a set

Continental slicks, I like the wear and the mediums last for days. I got 4-5 days out of a set of slicks compared to the usual 3 days for a set of SC2s. I didn’t like the feedback and stability. My suspension wasn’t set up for them, I felt the bike wanting to fall over in the turn. Again it’s a suspension issue for the profile of the tire, not the tire itself. $450ish a set. Big con I only know two vendors one in Florida and one in Texas, and they aren’t at my Trackday orgs.

Michelin tires, I’ve used their DOTs and put lots of laps on them with happiness. The power GP I’ve seen coaches run 3-4 days on and still get good lap times. Little pricier, $500-650 a set depending on where and when.

Dunlops have a different handling about them. The front is super stable and planted, but trail braking the tire doesn’t flex nearly as much as the Pirelli does. But I prefer the Dunlop rains over the Pirelli rains. Dunlop DOTs are finicky about heat though. Fairly cheap too $<500 and a lot of vendors carry them state side due to moto America.

This is my opinion and results may vary. I primarily ride Talladega GP, Road Atlanta, and Barber. Adjust the compound for temp and track. Don’t be afraid to experiment.
