Elite status miles are based on the BASE miles, not FLOWN miles. So you'll effectively get 0.5x on LA Q and 1.0x on JJ.
Remember that elite bonus does not count for status qualification. So if that is important to you, you'll get 0.25 EQM and 0.125 EQP (!) on LA, and 1.0 EQM and 1.0 EQP on JJ.
Either way, it seems JJ is better.
