Kaesemeister: One question though: Would you recommend using Linux Mint over Ubuntu and is it hard to migrate from Ubuntu to Mint? Thanks in advance.
I do recommend Mint over Ubuntu, as it's a lot easier to use and in my experience generally just works better overall than Ubuntu (although I haven't tried any Ubuntu release newer than 16.04). "Under the hood" Mint basically *is* Ubuntu, but with various tweaks, fixes & enhancements and a different desktop environment/UI, so just about everything that works with Ubuntu should work just fine with Mint.
Migrating from Ubuntu to Mint should be very easy - just backup your user data & then restore the stuff you want to keep on the Mint install. If you use any software that's included with Ubuntu by default but not Mint then you can simply install it from the system repositories through the software manager.
