I tried to stick to Prusa stuff through the release of Bambu products in order to support the notion of a group that can give-take within the OSH concept -- now they offer zero value comparably.
The Bambu products are better if you're willing to buy into proprietary stuff and you're not willing to put the leg-work into building something proper-open like a railcore.
Really sucks, but the writing has been on the walls for some time -- it has been harder and harder to find source/designs/models/etc regarding Prusa machines since the MK3 period.
