6 has been great. If you are a windows or mac user, it's very close to that experience and very familiar.
Can't say the same of Windows or Mac OS.
I really enjoy that it showcases all the work that goes into making a desktop actually good, even the small things you bearly notice, things like "When a grouped Task Manager task is flashing to get your attention, opening its group popup now reveals which specific window wanted attention. (Christoph Wolk, plasma-desktop MR #4225)"
A change doesn't need to be big and flashy and make headlines, even small changes deserve to be showcased and credited
And yes, a lot of work goes into the small things.
It's crazy how slow and bloated windows has become over the years.
I asked in the Linux IRC channel some help, gave my root account to a helpful user and very quickly learned about computer security.
