Best way to manage packages?

I'm trying to get familiar with Linux. One thing I struggle currently is managing packages. Native Linux package managers need tiresome work if I want latest versions. (Find and Add PPA or repository, Update, ...) I tried Linuxbrew, but it's **error prone** unlike Homebrew on macOS. How do you manage your packages especially if you want **up-to-date**? I'm running Kubuntu and openSUSE Tumbleweed for moving from macOS to Linux. Are PPA things fine with you? Or Linuxbrew works fine with you? Or ... How do you guys manage packages on Linux? There's no better option for that? Or ... Any opinion, advice, suggestion, your experience, ... are welcome!
