There is one UA flight and one LH flight.
It's really impossible to predict odds in the abstract, flight loads change from day to day. But in general, the UA flight SFO-FRA is a very difficult upgrade. The LH flight has almost twice as many business class seats (but requires a higher fare class).
If the upgrade is really important to you, the advice upthread is to look for a connecting flight (i.e., IAH-MUC, ORD-MUC, etc.) with R available at booking.
