Hi Harry55, and welcome to the forum
My suggestion would be one of these 5 in this order
Linux Mint (Cinnamon)
Linux Mint MATE
I must add I'm part of the Peppermint team, so read into that what you will
Any of those 5 would be good choices, so why not try them all out on LiveUSB ?
A LiveUSB allows you to test drive the OS running from a USB stick without making any changes to the hard drive .. if when you find one you like, the USB can then be used as the installation media.
Would you like assistance with how to download a distro ISO image and 'burn' it to a LiveUSB stick ? .. if so, which would you like to try first ?
