I did not. I have a Creality CR10 and a lot of experience working with the Ender series.
I specifically wanted something that would just work out of the box, no fiddling or tuning or upgrades or buggy firmware etc etc. Creality makes some great budget devices but the money you're not paying them goes to refinement and idiot-proofness with other brands..
Plus I'm moving on to working with exotic materials and multiple materials in a print. The Bambu covers all of those bases. With a single materials station you can mix 4 materials in 1 print, and you can even combine stations for up to 16. And it's really, really, REALLT fast. The big hangup is its a closed ecosystem with their own slicer, black box firmware, most components have to be bought through Bambu, etc. But like Apple thats how they ensure it works well, by having control over everything.
