Why Manjaro instead of Ubuntu?

As per my experience, I am able to perform some daily tasks easily and effectively using Manjaro (I have used Ubuntu for approximately more than 2 years and Manjaro for about 1 month). By the way, I am a programmer and technical person, but here I am sharing my experience as an end-user and a functional person who just wants to get things done.

1. I generally use one monitor or two monitors and frequently switch between them. When I switch from one monitor to two monitors or vice versa, I need to change the sound output (I prefer the second monitor for audio when available). Every time I switch, I have to open the Sound Settings and manually change the sound output in Ubuntu. However, when I switched to Manjaro, I noticed that all available sound devices are accessible in the quick action menu (top right), allowing me to change the sound output directly without opening the settings. This is very convenient for me. (I am not sure if Manjaro requires manually changing the sound output device as I haven't used it extensively, but even if it does, it's still better for me because I can change it from the quick action menu.)
2. I like alarms, timers, and stopwatches, and I frequently use them on my mobile (though I use my mobile less). However, I also wanted to use them on my desktop. In Ubuntu, I found this functionality, usually through terminal commands and some GUI tools (though I haven't tried them). But when I installed Manjaro, I found these tools already installed by default and working smoothly—alarms, timers, stopwatches, and world clocks with multiple alarms, timers, and other basic and intermediate functionalities that I like. I think I could achieve the same in Ubuntu by installing a package, but Manjaro showed me this feature out of the box and opened the path for me.
3. I use Bluetooth frequently, mostly to sync and connect devices seamlessly. When I used Ubuntu, I connected my Samsung mobile to my Ubuntu system (connected for audio and calls). It worked well for audio and music, but when I received a call and answered it, the audio was not audible to me (not sure if I was audible to them). However, in Manjaro, it worked without any issues. I think I could make it work in Ubuntu with some effort, but this feature was not important enough for me to invest time in fixing the issue.
4. In Manjaro, my laptop touchpad works very well with all gestures, such as two-finger and three-finger gestures, and it also provides options to adjust and customize settings as per my requirements. In Ubuntu, the touchpad didn't work as seamlessly (though I know it can be configured), but this feature was not important enough for me to put in the effort to fix it, as I generally use a mouse.

Why not to use Manjaro?
