I've used Linux for 15 years. It truly was a pain getting things like ADSL modems (wired) connecting. But that was 15 years ago and not the point of this post.
I use Linux at home -
Gnome gives me no task-bar, or a highly customisable one if I want that. I'm focused in the application that I'm in. The UI supports the *NIX philosophy that one app does one app's job well, and if more need to be binded together, that's OK too. I feel peaceful in Linux. Terminal is running and that's an alt-tab away. Mouse to the top-left gives me other apps, though only ones I regularly find useful. Mint might not give the same.
Linux, or my Linux setup, allows me focus.
I use Windows at work -
Windows has a taskbar. Everything is in the Windows menu. The taskbar can be hidden but mouse-over activates it, and the Windows menu can be customised, but it still feels there as a distraction. Office is an outstanding piece of software today; Outlook: I used to receive 400+ email per day, and know people that get 2000+ everyday too - Outlook makes that almost manageable; Excel and Powerpoint are astoundingly good at their scope; Word, I transitioned to pmwiki (need for collaboration and flexibility); Sharepoint and AD integration... obviously this is a corporate environment.
Windows feels distracting. Adding a Linux sub-system doesn't change this UX (for me).
What works for me -
In a working environment I have Linux running on a VM and spend 60% of my time in this. At home I have a Windows VM running 20% when I want the best of Windows (which, for me, is Office). Not a gamer so no input there.
Choose the most comfortable tool for the job. YMMV.
