Prusa is king. High quality. Open source. EU made and engineered. Slicer is a market leader (Bambu's a fork of it).
But it's a premium brand now. For lighter use by hobbyists, Bambu is the clear winner on price/performance. The 'less open' downside is not a factor to most people, and the printers generally work so well out-of-the-box that repairability isn't as much of a concern as it was on printers of the past.
Personally I went from a Prusa MK3s to a Bambu P1P (after looking long+hard at Prusa options), and so far, no regrets. (Although I've kept the old Prusa as a 2nd printer and upgraded it to a MK3.5, but mostly just because I do enjoy a bit of tinkering with them)
