Linux Mint Cinnamon is comfortable and comprehensible for a Windows user.
Unless you need to do some actual work, in which case it's useless.
Yes, totally useless...
Most Hollywood films are now edited on Linux and have been for a while (particularly animation and lighting).
The internet runs on linux.
Most businesses have moved more and more online (Linux servers) and accessed through a browser which tends to be universal.
I have all my 3d printing and CNC software running native on Linux and Mac.
Photoshop? I have CS6 running in WINE on my desktop (I hate CC) but GIMP is actually making inroads at schools. I also use PhotoPea which is like a free online Photoshop.
You can run Fusion 360 on Linux through the online version, WINE, or with a VM (Mac or Windows). There's also a few others that run native or in a browser dsuch as Blender, Tinkercad, Freecad, Brickscad, and more.
What can't I run?
A few AAA games
Microsoft Flight Sim 2020 (may be possible now, I haven't looked)
Solidworks, this is not due to technical reasons but because they really hate it running in any form other than native bare metal and put in several system checks to stop you from doing it. The last version I used it wasn't even allowed to run in VM which many had been doing for years.
You're ideas about Linux are about 5-10 years behind the reality.
That isn't to say it's an easy switch, the more you know about Windows the more difficult the transition which is where most people get tripped up. They get frustrated because they know how to do it the "easy way" on Windows and want it all to be that way on Linux. The truth is, every OS has it's highs and low points. If Windows works for you, great, but you get over this idea that everything else is useless. Even Microsoft acknowledged that the desktop OS's days are numbered, not that it's dead or going to die, only that it's disappearing into the background and that what OS you use is unimportant. Which is precisely how it should be. When you use a browser do you care what OS it runs on? When you edit a photo do you care what OS it runs on? So long as it runs, who cares what's behind it.
