If I only wanted to degoogle and disable other manufacturer’s bloatware from my Android device, is using adb to “uninstall” the system apps from user 0 pretty much as effective as rooting and using something like debloat terminal while rooted or are there bypasses that make rooting the better option? I’m not concerned about reclaiming the space used by these disabled system apps in this case.
adb uninstall will cover your needs and if you are using a banking app they won’t let you use them if you root the device. So even if you choose the root way, it’s recomended to relock root once you’re done.
Also not sure about stock ROMs but be careful with core apps. For example, in LineageOS if you remove file manager that way you bork the system because any other file manager use the initial file manager.
