@easyt50 Please don’t drive yourself mad. Despite the valuable remarks by @Andy2 and @Akito in Large Updates you shouldn’t make your life more complicated than it needs to be.
If I were you, I’d go, whenever possible, with your software centre or your standard repository via sudo apt install xyz.
The main things you should avoid are installing software from dubious sources or typing in some random commands, just because some guy (or chick 
) on the internet tells you to.
I guess, you use your computer for entertainment and productivity. In that case, you shouldn’t hardly notice which operating system you are on.
In case you really want to dig deeper, nobody stops you from reading and experimenting, just take everything you read and hear cum grano salis - including what I say.
