Does the unbranded stable build have automatic updates yet? Last time I checked (which was quite a while ago) it didn't, which made using it day-to-day seem like a bad idea. I'd totally switch to it if I can just use it normally.
This updates frequently since it is basically Firefox beta (though in practice i never had any issue). Note that this has telemetry enabled by default so you may want to disable it via the options.
The unbranded stable isn't updated automatically so you'll need to check for new versions yourself (shouldn't be too hard to automate it with a python script or whatever that runs via cronjob or windows task scheduler and notifies you for new versions).
I think the argument is that if you’re knowledgeable enough to write an extension you can switch to the “I know what I’m doing version” and let everyone else reap the benefits of malware protection.
