I wouldn't say that everyone wants the bus. The guys who want the bus either want to be in a base that is only a bus base, or for some reason value the size of airplane over QOL. I've been there for a little over a year (15 months) and I'm more than 50% up the list in Boston on the 190. I was on reserve for 4 months. You'll make more money on the 190 because you'll be a line holder sooner, and after 2 years you can bid over to the bus if you want. (People bidding over is why you move up so fast on the 190.)

If you live in base and just loooove red eyes, bid the bus. Otherwise I'm not sure why a new hire would want it. Obviously if you live in FLL or Long Beach, it makes sense. If you live in Boston, go for the quicker movement. At least, that's what I would do if given a choice.

FWIW it just depends on your class makeup as to whether you'll be able to hold the bus. Sometimes it goes junior, especially if the class is full of commuters that understand it will get them off reserve sooner, and make their commutes better.

Good luck!
