Personally would go for QF, have worked for BA World wide and Euro fleet and did not like the airline and hated going to work, you were just a number at the end of the day and depending on fleet and base I found BA the most islolating job I have ever done, worked for 2 previous airlines before that and loved every minute of it so think I was expecting the same. It is personal opinion but I would never work for an airline again with so many crew as you never really get to know anyone - thats personal opinion though. Think QF have a good size base and great crew and the basic is higher also promotion especially at LHR will be allot quicker.
