I've got the complete opposite to you. I'm in a household of 3 gaming desktops and 3 laptops, plus family who need help. I've been daily driving Linux for about a decade now and keep duel boot around just for Adobe products.
On all these machines, Linux hs been rock solid and never had issues that wasn't user caused. Windows on the other hand drives me crazy with how much it fucks out. I have next to no control over it. It updates when it wants. I have no control over what's updated. I hate the gods damn ads (and that's on Windows 10) despite running de-crappifying software. I hate how many errors it has and how long it takes t troubleshoot them. I hate that if the system borks itself enough, it's faster and less insanity inducing to just reinstall the whole os than try and fix it. I hate that Windows just gets progressively slower and laggier over time whereas my 6 year running Arch install was as fast as the day I installed it.
Obsidian can be almost anything you want it to be. Try searching out some videos from folks who use Obsidian for journalling.
