Hi there i'am using Linux think it must be 10 years now.
I used a long time Ubuntu 12.04 with Unity, different versions of debian, openSUSE and a short time Antergos, Manjaro and Vanilla Arch and many Versions of Linux Mint.
All Distros have a Problem openSuse ist very Slow 15.3 KDE give me a black screen and do not work on my 3 PCs. Linux Mint work from 17.3 for me and with 20.2 i see again cinnamon crashes.
So i decide to try Zorin OS and i like it, i not a big fan of Gnome i always used KDE Plasma and Cinnamon Gnome runs always slow on my PCs and Zorin is the only one that work good for me it is really fast and i was surprised seeing gnome so fast.
I'am a private person and have enough times setting up Linux new and fixing problems.
I only wish a easy to use and stable system and Zorin is this for me.
After a Week of playing with the Core Version i bought the Pro and now i'am using this on my old msi Laptop my newer asus laptop and on my desktop PC and it works good on all 3 PCs.
Only one suggestion i have for the DEVS it look a little bit ugly update the os with canonicals update tool and Software with Gnome Software.
Take a look at the Linux Mint Update Center and create your own for Zorin OS so the User have one Place to Update the system and programs my personal thoughts the Mint Updater is the best i ever seen in Linux.
This is the only point in Zorin OS looking not pretty.
