There’s quite a thorough debate about the Bambu vs Prusa in the New mk4 is out-thread
Short answer is: Bambulabs is great engineering at a great price. Cutting edge stuff. But - many solutions are proprietary.
Prusa is great engineering and open source community driven development at a little higher price, and currently at a slower pace of adaptation. If you want to support open source community and tech and have full access to all hardware and software details (for modding and such) Prusa is the way to go. If you want the latest and shiniest machine to the lowest price Bambu is a great contender.
