For general purposes, don't use beta. It sounds like a stable release is what you want. You rarely get benefit out of new features, unless you already know what they are, and then it crashes and loses your work, etc. etc.
I often run betas, as a tester. I am involved in several of the lower grade private betas for Microsoft. My computer is messing me around a bit at the moment, but I was having an issue with MSE 2 beta. Upgraded to version 2, and the problem remains. I now cannot format my computer until Microsoft are happy.
Without going into details, MSE is repeatedly failing to remove an Eicar Test file (com).zip as "Not Found" but then finds it again, removes it "Success, Not Found", finds it etc. etc.
This install is getting old, and a format would be great, but I can't!
