Debian the Winner
I am writing this with Live Debian Gnome Session, while installing the same on a external hard disk, that I recovered from by ripping off two of my 32 bit computers.
I actually pulled out even the motherboard so that I could use the metal frame of the desktop and tower for a slipping footsteps (it is raining cats and dogs now) to our home.
Barring the superlatives, most of the new Linux distributions I could not install, probably due to faulty Grub Software.
They include, PCLinuxMagnum, Open Mandriva, Peppermint-10, Absolute Linux and even Ubuntu.
However the Ubuntu derivative BackBox (for hackers) was OK.
They are not for my PC and probably for only Laptop installation.
My laptop runs on Debian 10 but my PC runs on Debian 9, perfectly OK, I won't try installing 10.
So for fun, I installed Debian Plasma (lovely desktop) and currently installing Gnome Desktop.
By the way, RubeccaBlack probably a derivative of Open Mandriva is an excellent Linux distribution (short on packages, though) to try.
They all have plasma desktop and RubeccaBlack has a lovely new Western Desktop.
Neat Work.
Thanks all boys and girls of Linux Developer Crowd.
