I advise against getting the brand new thing. My experience has been that frequently the reliability and feature set of yet-to-be-released things tend to be highly overstated. The CORE looks cool but I would give it six months after release before you consider buying one so you can see some real reviews.
Prusa has a pretty decent track record but they are really branching out of their comfort zone now and I would be cautious.
If you don’t want to wait, the Bambu P1S is a phenomenal printer. I wish they were more open along with everyone else but I have many, many, many hours on mine and has been an excellent purchase. It was a massive upgrade from my Prusa Mk3S.
The XL is indeed corexy but it’s also marketed to professionals who would be able to navigate any issues. I’ve seen some mixed reviews on if it’s good.
FWIW, Prusa has definitely had some major failures. The MMU2 was fundamentally broken on release with sensors that were unreliable at best and the community had to step in with replacement models to get it even somewhat reliable.
Just be wary of trusting the brand. I like Prusa too but they aren’t immune to misses.
For me, pre-purchasing a Phrozen resin printer that every single YouTube influencer assured me was the absolute best printer ever made only for it to be an absolute mess that just sits on my shelf unused because it is complete garbage, was my lesson to wait for the reviews.
