If Star covers many routes unavailable from Delta's Air France/AeroMexico partners, this is certainly a reason to choose United. However, if the routes overlap Delta is the way to go because elite Delta status earns the appropriate mileage bonus on Air France and AeroMexico. UAL premiers earn no such bonus on partner flights.
UA's
website indicates that you do receive the bonus on LH-operated codeshares under the current program. The 2000 program details are not yet posted, however, so perhaps this is changing next month...?
