Datadog has browser log collection and RUM browser monitoring...

They both allow applications to log browser console errors and request errors.
The RUM monitoring looks a lot more comprehensive, so my question is, what does the browser log collection do that RUM does not?
I am struggling to see why someone would need to have both.
