Catalina experience up to patch .6 was a huge fail, especially since it happened during the pandemic and my 2018 MBP was becoming unresponsive during long work hours and meetings and crashing, fully restarting on its own around 2 times per day. Big BT issues also, at some point I had to reinstall the OS to fix them. Big Sur was just fine and Monterey brought back BT issues... For someone jumping to MacOS 3 years ago the experience is just 50% either way which is not good
