Your MBP won't run Big Sur, so you're already falling into 'legacy' territory. The 'best' OS is the one that lets you run the apps that you need, while supporting your hardware. Test booting into Safe Boot Mode (hold down shift at boot), or running in a brand new user account that doesn't have all the Login Items and Launch Agents of your existing account. Or it could be that the slowness is caused by software: things you've installed, possibly for a previous OS, that now don't play well on Catalina. If you haven't already maxed it to 16 GB, do so.

If you still have the original hard drive, then that's the likeliest cause of slowness, and it should be replaced by an SSD - to improve reliability, if nothing else. (Indeed, one of the reasons they cut off older Macs is because the new OS doesn't run well.) If Apple says an OS will run on that Mac, that means it should run fine. Your question is based on the premise that it is the OS that is causing the slowness.
