Is "favor" mostly used with the preposition "over" when used as a verb? Like "favor A over B?" What's it mean?

When "favor" is used as a verb, it can be used with other prepositions or without any prepositions at all. However, when you want to explain that one thing was favored more than another, you can use the preposition "over." If A was favored over B, it means that A received a better outcome than B. Ex: Private schools tend to be favored over public schools. Ex: The employees favored shorter working days over 4-day work weeks.
