which type of blur should I use for situation x? If I have 7 choices, deciding is hard and confusing unless I know what they all do. If I have 1, I just try to get what I want with it

Lightroom providing a limited set also focuses people in on the most important ones
while not confusing users with less used or more specialized tools
