IME, the queues on the Eagle’s Nest side can be worse because most of the passengers arriving there want to take the bus, while at t4 or t5, you have passengers arriving at more gates, but only a small portion from each arriving flight will typically go to the bus to the nest, along with the LAX originating passengers who will also get to the bus stop as they arrive.
If you arrive on an Eagle flight right after several other flights you can find yourself at the end of a long line and wait for several buses to come and go.
