For those worried about security, (without fuss) how about something like:
Btw, Solus beats any distro at boot/shutdown speed, hands down!
GUI (along with any program included) is definitely still hard to surpass in esthetics.

Graphics wise - not as good as on Windows, nor as good as KDE versions like Q4OS etc. but still pretty decent (and better than MX 18).
