I’m thinking of choosing Debian instead. I’m a student, low on budget, and wanna play with linux and laptops, and I think Arch or Cachy OS need updates or distro upgrades(?) weekly or something?
Solved: up to date Arch can last for 2 decades on my cheap laptop, and use Flatpak for older versions of software.


Both the system have updates which are often rolled out. You can choose not to update, or can set the system to update automatically. You shouldn’t be worried about updates. The os will keep on working on your laptop regardless of how many updates it receives.
Unless by low budget you mean a 2010 cheap laptop, you won’t have problems with either of the systems.
Can confirm. I have an old 2015 laptop running Bazzite, and it still updates and runs like a champ (and though that’s Fedora, it should be functionally identical to Arch or Debian for most things).
