Upgraded to a 64 bit OS (Catalina) a few years ago from my 32 bit OS but it has never run well and actually is embarrassingly slow. I have another new machine but still want to use my old one. Is there a 64 bit os that will make it run better?

Apple has been shipping 64-bit macOS for over a decade and these supported compatible 32 and 64-bit applications through macOS Mojave (10.14.6). Starting with macOS Catalina (10.15.7), the operating system only supports 64-bit applications.
Your previous Mac cannot install an operating system older than what it shipped with, and factors such as CPU, drive type (rotational, SSD, or Fusion), installed RAM, and application mix will determine how it performs regardless of the operating system. Don't run any resource-hogging anti-virus software on it.
macOS Big Sur or macOS Monterey but if that MAC isn’t compatible with these macOS and Catalina only then you don’t have choice to install macOS Catalina
Thank you for your response. I am on Catalina 10.15.7 (latest release) I spoke with a friend who was an Apple Genius team member who said similar things about increasing RAM and replacing my hard drive with an SSD. Fortunately, I don't have any other apps on the machine. I will go with the SSD first. Thanks again.
Best MacOS for 32bit machine
