opi VS osc

This is incorrect. It also installs a set list of packages.

Have you looked into OPI? This allows you to easily search and install community packages from the Open Build System similarly to how it is with working with yay on Arch. It very likely does not contain things like git packages or fonts but it can be pretty useful for packages like ckb-next and since it pulls from the OBS it is always guaranteed to be a binary, no compilation necessary

As of this writing, opi performs the following operations behind the curtains (see here for reference):

opi will implement a workaround in https://github.com/openSUSE/opi/pull/120 which will force the ffmpeg version on tumbleweed to be >=5.

OPI is your friend. You don't have to update every day...once a week or so is fine. Set up multiversion for kernels. A lot of times if a vendor offers a Fedora RPM and not openSUSE, the Fedora RPM will work fine. If you are using Nvidia, wait to update kernels... that's all I can think of. Use and update the wiki as needed, it's a good resource, but can get outdated.

Yeah I'm pretty sure it's using Packman https://github.com/openSUSE/opi

OPI is also useful for finding other packages that aren't in the regular repos

The easiest way to install software is with OPI, you can also search with Zypper or YaST. Generally, if you can find an RPM file built for Fedora, you can install it on Tumbleweed as well - I'm sure there are exceptions.

https://openbuildservice.org/ is one way to produce distribution packages across a wide selection of distributions, if your source code is open.

As fair as I understand, OBS is indeed a suitable replacement for AUR right now.

OpenBuildService is better in every way, is fully opensource everywhere and can even generate packages for ubuntu better than launchpad appears to, and can even build entire distros. No special integrations are necessary, it can cost-effectively work with a highly paralellized number of virtual machines (iinm 100 or more on generic threadripper or epyc).

Suse's OBS is another option, and there are likely others...

Good idea, give it a try. I'd recommend Kubuntu or Mint with Cinnamon. I switched to KDE for KDE Connects' amazing smartphone (Android) integration, which i recommend srrongly to try. Switched to openSUSE Tumbleweed myself, best KDE implemention IMHO, rolling release and the software selection is great, whats missing from the repos can be installed via opi, a client for [0]. It is not that newbie friendly though, since SUSEs' focus is on the enterprise ie safety over ease of use.

Try it on openSUSE, the best KDE integration by far IMHO, since it is their standard DE since IDK/forever? Tumbleweed offers the newest packages, rolling like Arch, but with a huge test battery on OBS (https://openbuildservice.org/). Snapshots on upgrade make the thought of breakage (haven't had any) tolerable.
