after trying both Manjaro and Linux Mint, here's what I found.
Personally, there are things I found easier in Manjaro, such as using KDE Plasma versus Cinnamon, but Linux Mint was also more intuitve in some ways.
The display options are easier to use in Manjaro and it handles the scaling options quite better. Also the "Magnifier" -the name the Magnifier app receives in Windows- is a feature already enabled by default, which you have to enable in a separate option in Linux Mint.
Something I loved about Linux Mint is that it already comes with a default text editor and a Notes program. I especially missed the Notes program in Manjaro.
At the same time, Linus Mint by default misses some features, such as the Font Manager. You can install them manually and all that, but Manjaro recognizes the .otf format by default, while Linux Mint doesn't. In Manjaro, it was like Windows: you click on the font and the Install option appears; in Linux Mint, nothing at all.
I like the update manager better in Linux Mint, and well, it doesn't give strange errors like it did in Manjaro, where it told me there was an update pending, but then you looked and in fact there was nothing, and the solution was to refresh the database.
Manjaro has more package managers -but I don't like too many tbh- compatible by default, but I liked the software installation in Linux Mint much better. Since it's based on Ubuntu, some programs are super easy to install.
I used the Terminal for both, but it's actually fun, although I noticed I lost some skills using the Terminal, when I was studying I knew a lot more commands and how to handle Linux much better, my scores weren't that bad in Linux exams.
Sound management seems much more natural to me in Linux Mint. In Manjaro, you see a ton of devices, and sometimes you don't know if you're choosing the TV, PC speakers, etc., because it lists Pro Audio and a few outputs but the names aren't clear, while Linux Mint only lists the devices that are actually needed.
Manjaro doesn't come with an email manager. Linux Mint comes with Thunderbird, which I had to download in Manjaro. Still, my favorite is Outlook, but hey, I use the SPA version or a browser to log into my Hotmail account, and I can get by without it.
Then, in programs like Telegram or Discord, Linux Mint gives me much more security. I mean, those two apps work perfectly in both Manjaro and Ming, and I pin them to the taskbar. But in Manjaro, even though it indicated that if I close the program, it shouldn't remain in the taskbar or as a background apps, it showed you the number of messages you had in Telegram or Discord, and I don't like that. It gives me the feeling that I didn't have them closed. Linux Mint, on the other hand, shows you the icon in the taskbar, and as soon as you close it, you see a normal icon without message numbers or anything. Simple and intuitive, and you know the program is closed.
Mouse options are much more intuitive in Manjaro. The mouse in Linux Mint is fine, but the cursor options are harder to find, and you have to select the pointer in the appearance options instead of the mouse, something that is more natural in Manjaro. And a very good idea of KDE Plasma with Wayland in Manjaro, which I miss in Linux Mint, is that if you make quick circles with the mouse, a giant mouse cursor suddenly appears. It's a very nice touch. For some things,
Linux Mint sped up everything, for others stuff Manjaro Linux was faster or more intuitive. Both are my favorite Linux distributions. Ubuntu isn't bad either, mainly because it was the one I learned and studied Linux with back in the day, and that always helps.
In regards to games, I still don't trust Linux very much to become my main OS for gaming. Not that I care. Still, I gotta say that things seem to have improved a lot compared to 3 to 4 years ago when I used Linux exclusively for everything for a a few months. The games I tried worked flawlessly. The most recent one I tested is Legends of Eisenwald at 4K, and it ran fine.
