Toy Story lot, the busses come about 30 seconds apart compared to as much as 30 minutes apart for the trams to M&F and most of the time they redirect to Lion King (which has no shuttles at all) or Toy Story anyway unless you are disabled or need an EV charger. Also, the trip from Toy Story is a little shorter time wise, plus if security is busy, they have started offering a no bag line at times, which does not happen on the M&F side.
