I am curious. Why the other Linuxes? (Linii?) I know people do that -- but I never knew why. I just settle on one for a bit, then hop away when I get in a mood.
Different distros have different hardware comparability (esp older hardware) and different maintenance requirements. Arch requires an update, check on arch page for further requirements, and possible follow up, as well as updates to AUR packages which are git based. Other distros are often "click update in GUI and forget". So for your main driver, maybe you're happy to do the extra work. But maybe not on other devices with varying hardware.
