Three versions of Geary. Which should I use and can it be done?

Background: After experiencing so many stability issues and frequent crashing with v40, I thought one of the newer versions might be more stable. First, I looked into removing the original Geary, but quickly realized that it is part of the core components of the L5. They strongly recommend against removing it, and for good reason.

I did uninstall Geary and used another mail client.
In my case I never noticed any side effects from uninstalling it.
To me it’s just an email client, on top of the OS.
