I have an Ender 3, Ender 3 v2, CR10s Pro v2, and a Bambu P1S.
I would recommend going with the Bambu a1 without hesitation. My Bambu is far and away the best printer I own and it's not close. They just work, and though I'm a techy guy and enjoy tinkering, I got really tired of needing to fix things on my non-Bambu printers.
