It does depend on the context but I mostly use the '2 hours ago notation'. Sure, if you're looking for a specific timestamp or something that happened 2 months ago, it's not useful and then I switch to the timestamp format. Majority of the time I care about stuff like what happened today, yesterday just to get the rough idea.
