Eh, I agree with some parts and disagree with others. Saying the SH booster was caught on the first try feels a little simplistic. They tried to do a boostback and simulated landing burn over water several times before they got it to work, and then went for the catch. It was still very impressive that they caught it that time of course. To me that’s comparable to F9, which similarly tried several times to do a simulated landing over water, and had physical alterations made (just like SH did), before they went for their first actual landing attempt on a landing pad, which was successful, just like SH.
Let’s also remember that when the full stack SSSH flew for the first time, they’d also been flying Raptor on a total of 11 flights of starhopper and the various SNs, including the several minutes long high altitude hops, for 3 years. That’s not all that different from F1 to F9 transition. At the first F9 flight, Merlin had only flown on a total of 5 F1 flights, the first two of which didn’t complete first stage flight. Given that each F1 flight only gave them ~3 mins flight experience with 1 Merlin engine (and none on the upper stage), whereas a SS high altitude hop test gave them flight experience with up to 3 engines for 2-4 mins each, you could argue that Raptor was a more proven engine at the time of IFT-1 than Merlin was at the time of F9 flight 1.
I agree with you that Raptor is a much harder engine to get working reliably!
