Tbh I am a messy person, I trained myself to be organized but I still struggle to not lose my keys and I want something like the apple tag but FOSS, I've thought of an ESP32 or ATTINY with a bluetooth module but I don't think apple uses that? It has to be durable and friendly with LineageOS, samsung stock and my dad lol.
TL;DR: Want consistancy? Setup a server. Want a desktop? Pick a distro which seems fine, you can easily switch and distro hop. Don't let others decide, you are _libre_
Every experience is different, that's the beauty and the curse of Linux, you may be able to get consistent results on the same hardware (or similar), but it also depends on your own choices.
You may get 5 laptops in which Linux Mint works better than anything you have seen before so you say "I'll try this on my main laptop!" But sound disappears... weird thing is, 1 hour before you were on Arch, listening to music while playing Minecraft with your friends.
Yes, the last example is taken from my own experience. Personally I think you should start picking a distro that looks pretty and easy to pick up, pick Manjaro if you want, don't let others decide for you. And, if you have the chance or money or whatever try to setup some servers, could be a RaspberryPI a random laptop or even a PC you found in the trash (again, yes, I did found a computer on the trash).
If you really want to learn linux you must learn by experience, that's why everyone contradicts themselves unless you get on server administration, NixOS, etc. You can get consistent, if you want that, start at server administration, install any distro and setup some services! How could you use rsync to make backups? Are you sure you want SMB? Why not iscsi? Why not benchmark them? Have you ever tried playing a game storaged in a server in your network? Well, iscsi and 1 Gb networking can make that work!
On the other side, if you just want a desktop you should try distros by yourself, for most of them a VM or Ventoy is enough, do you like Mint Cinammon because it's Windows like or want a Mac like feel with CuteOS? Maybe wanna try something different with Manjaro Gnome? Why not test all? Arch intrigues you? Pick a VM and the Arch wiki! If you want to try distrhoping I advise you to make a separate home partition and backuo your files. Not "if" you mess up but for when you do, cause you will.
