From what I’ve seen the Bambu might do better prints - but having started 3d printing with a Flashforge printer a few years ago with the main issues I had related to their closed source slicer and some problems with spare parts I’d never buy into a closed ecosystem again. And Flashforge was doing variants of open designs, so you still could put in more effort to rebuild parts to non-Flashforge-components on issues - no such luck on the Bambu.
