If you're rating depots by efficiency, BNDEP last (Recall the
black patches that are so obvious on DDs? How many months did it
take for the resolution of the black patch? Also recall B9TL
deployment. How effecient was the depot management?)
Compared to BRBP, BNDEP effeciency was a let-down. EDS of 9810X on
143 on its initial days displayed TPY Teban Gardens. Resolved
within 6 days or less. 
If you're rating depots by choingster buses, SLBP actually last
(let me recall when a SLBP bus I took sped over 60. Maybe there
are, but I haven't found yet)
If you're rating depots by number of crazy cameos (I think some
are), that is crazy.
If you're rating depots by ride comfort, unfair due to the various
models of buses. (recall C & C, how can you compare apple with
orange, or compare taste of apple with the colour of orange and
call it a difference?)
If you're rating depots by maintenance, I DARE SAY SLBP will
somehow be on the upper half, or even top, while depots like BNDEP
actually jia lat.
If you're rating depots by the friendliness level, you've to be
friendly first and greet the BC. Only then do you have the right to
say this BC rude, because he doesn't reply to your greeting.
If you're rating depots by how fast THEIR service guides
appear/disappear, get a life.
If you're rating depots by how many chiongster buses in that depot,
you're mad, I must say. That kind of rating is truly
unreliable.
