TCs, yep. If you can afford the outlay, it's worth it. The only reason I haven't replaced my first pair is because Specialized have price embargoed them in the U.S. and they cannot be sold for less than $80 each. Which is just too expensive. I got 2500km out of mine before I started to puncture. Corsa's were like 1000km before they became puncture magnets. Terrible.
I don't see how a clincher gets better than a TC. It's not as fast as a GP5000 in a straight line, but my god is it nicer to ride. And corners better IMO.
Don't buy FMB open tubulars. They have terrible, terrible quality control, are short life and the tread constantly peals away from the cotton casing. Challenge are notorious for punctures, too.
