• Proton & Lutris
• Libreoffice & Nextcloud
• G.I.M.P, Inkscape, Krita
• It's cooler, more secure, more private, more trusting etc.
• More compatible than Windows 11 that's for sure

The first three boil down to, “If software that you need/want only develops for a specific OS, use that OS.”

It’s time we stop blaming linux for vendor choices.

Gaming: Only if you're playing one of the VERY few games that doesn't run in Linux yet, and that number continues to drop rapidly. There's plenty of tools out there to make games work well in Linux.

Office: For basic things, there's a million and one office suites that work in Linux and you can even use Office 365 Online if you really need that Microsoft Office experience/compatibility. This is only valid if you or your company need specific add-ons that don't have any equivalent in other office suites. My own employer uses these, so in that instance, yes, I do need MS Office for those. But from what I know, still not an entirely common thing, and you can still get by with Linux compatible office suites for most things.

Photoshop: I don't work with images, but from what I understand this one has some validity, comparing the tools available in Photoshop vs the GIMP or other drawing tools. But that's just if you're doing some really advanced image editing.

Ecosystem: if this is just referring to the fact that most people don't use Linux, there are plenty of FOSS programs that work in both Windows and Linux and very few common file types that aren't mutually compatible.

Hardware: another instance that has greatly improved over time, and there hasn't been anything in years that I haven't had "just work" by plugging it in. If the proprietary drivers don't install, there's probably an open source driver out there to get your hardware running. Will admit that in some instances features may be more limited, depending on what the drivers will be able to do, but as I mentioned that's really getting better almost daily.

Gaming... yeah it's not like there's a dedicated portable hardware device for gaming that runs on Linux by default.

MS Office, well it's literally a Microsoft product so yeah, though O365 does work.

Photoshop I haven't tried in years to run on Linux but I wish haven't bothered with Photoshop in years period so...

YMMV

If you have an old nvidia card, you're going to have issues with some games. BF4 for example, no matter what you do you will have lag and stutter

There's wayland and lack of support for nvidia cards, and major distros and GUI's dropping x11 in favour of wayland (regardless of whose fault it is or if it's good or bad in grand scheme of things, whoever has an nvidia GPU is going to be forced to use other distros or windows)

And then the whole proton and wine stuff... I just installed CoD 2 and had to fetch some commands in order for it to run, else it crashed after playing the first cut scene. And then there are other games, like Divinity dragon commander, that I couldn't figure how to get it to run. Tried several proton versions, none of them launched the game. My fault or ignorance? Perhaps, but on windows it would run first try.

Without knowing what you play, how many games would you say are as easy to install as under Windows and how many needed some additional encouragement?

The con of one of then being "is a rootkit"
