I'm currently looking for a new OS, coming from KDE neon and I like it, but the fact I have to FUCKING restart because someone decided to push an OS update that broke my previous install, now the OS freezes my whole PC (never did before!) and I have to restart.
I'm looking for good apps support so Debian? Idk
Using it for daily usage (Android/games development) and gaming.
I'm quite happy with Fedora. It has kde support, many apps (especially with rpmfusion), and is quite stable because it is still a 6 month ish major release schedule. Wobbly windows, kde connect, and krunnuer will definitely work. Good customization is subjective, and honestly I consider c/unixporn to be weird but cool wizardry, but I'm happy with it. One thing to consider is if you have a newer amd CPU with an iGPU being used it will get slow and crash every now and then (few months). It's a bug in the linux kernel starting around 6.10.
Try Aurora DX (it means the developer edition). It's KDE but with a Fedora base and immutability. It means that even if an update breaks something (unlikely but still) you will always have a working system available to fall back to. It does mean that development is meant to be done via containers, but I find this solution to be way cleaner and easier to work with than traditional package conflicts madness. Give it a go.
It also means updates are just full system images, so no way for a package manager or differential update to mess anything up. It also means no way of downloading tiny differential updates (if I understand everything correctly).
If you don't need DX or would like to switch off of KDE, there are other fedora atomic desktop based distributions available.
Oh right, a distribution is just an image, so switching distributions is as simple as switching the base OS image and rebooting.
Krunner, wobbly windows and KDE connect are features of KDE Plasma, not Debian. You can install KDE plasma on arch and use all of the things you listed. Arch also has good app support through the AUR. Plus the wiki is called the Linux bible for a reason
If you like KDE your night find endeavouros with KDE pretty good. It is an arch derivative so it is rolling release, if that is acceptable then I would say give it a try.
KDE is a desktop environment, you can install it on almost all distributions and it will look and behave same (yes can use wobly windows and krunner). I do not recommend KDE on Debian12 as its outdated enough that you can't install themes from kde's settings anymore.
Personally I recommend Fedora's KDE Spin, I believe its a distribution that you can install and forget and occasionally check for updates on kde's software center.
There's also arch based distros like cachyos or endeavouros with calamares installer that let you choose desktop environment before install.
I'll see if someone suggests me anything else and I'll try it. Not sure if it has the apps menu at full screen (macOS style) or not, not a big deal though
Not a fan of Macbooks but Idk how to explain it otherwise
For what you call 'MacOS like search' I'd recommand Recoll, working on any OS (and perfectly on my Debian install, for years on) : really can find ANY text string inside any document, from almost any app (e. g. Joplin, that I'd bet nobody heard of here), also including e. g. words within attachments within zipped backup email databases, pictures located on unpermanent backup volumes etc.
Regularly updated, that the one thing that definitely had me 'finally forgetting' MacOSX.
I tried Bazzite as my first try with Linux for a while and liked it; it was super easy. I didn't like that the immutability went so far as to lock me out of some parts of the OS that I thought should be open, like lock screen customization.
Now I am on Garuda Arch and it has been really easy too.
I see. Deb is definitely the most package-friendly.
GNOME combines Mac's "stage manager" and "spotlight" into a single function activated by the Super key (windows key/command). It's really excellent and probably my favorite thing about GNOME.
Everyone is recommending KDE, but forgive me if I'm missing something, I don't see it needing to be KDE support as a requirement on your list?
Any mainstream GNOME distro, eg Fedora, will have all the features you need through extensions (compiz window effect, gconnect for KDE Konnect, GNOME has the search you want by default and supports lots of customisation via shell themes, GTK themes, icon packs and extensions.
Gnome is ugly IMO and the extensions and custom themes to make it pretty break at each and every update. I just don't bother with it anymore. KDE was customized to my liking once and it stays that way through updates without any failure.
I also had kde neon and switched to kubuntu. Its really nice and only has minor issues. I also tried opensuse beforehand, which was not a good experience, for example the sound did not work (which is a typical probl, at least says their wiki and the fixes were obsolete, but not documented that they were.) and as a final straw, YouTube video played without hw acceleration, even with codecs installed.
I had less problems with endeavour os (arch), which runs on a second rig as a steamdeck.
