Here's a few other P/C to consider since you're within the 24 hr booking window:
LAX ground experience, you will be able use the separate F class lounge which has better booze and order on demand food. +1 OZ
ICN v TPE ground experience - BR lounge is pretty nice and has good food offerings, but ICN is a better airport DRAW (unless you are a beef noodle soup fan, than point BR)
IFE - OZ is like watching KTLA on a Sunday afternoon (you have to be an Angelino to get that), while BR you could stay up all night +1 BR
Amenity Kit - LAX-TPE is no longer Rimowa, but the GJ kit looks better than OZ offerings +1BR
Service Ratio - +1 OZ

To me, the question is what do you value most, and go off that.
