Recommendations / help

Recently just got back into 3d printing after finishing my basement My printer was running pretty decent printing with esun pla+ and cura slicer but my prints were really slow. I tried switching to orca slicer and bambu labs (both seem to be very similar) and I just can't seem to get prints to not be stringy and that's if I can get the prints to stick to the build plate, made sure to keep the bed clean with ipa and microfiber cloth. Should I just switch back to cura? I tried to duplicate the same setting as best I could After doing some research would it be worth to upgrade to klipper or marlin? Another couldn't seem to get the bed level with stock glass plate so I bought the magnet build plate to try and see if that fixed it
