Let me guess. You are one of those guys who bids to fly only on the -700 because it makes you feel important right? Look, from a pilot standpoint the -700 is a good airplane when compared to other regional jets. However, unless you are 5'4" or shorter the aircraft is terrible as a passenger. There is no leg room, the seats are hard, and due to crappy construction the person sitting in front of you ends up leaned back into your lap even if they never hit the recline button.
Boarding may be somewhat faster with no large carry-ons, but all it takes is one pax arguing about plane side checking a bag ("I took it on the last flight") and that is all thrown out the window. Deplaning is NOT any faster unless you have no carry-on bags because you have to wait longer for the ramp to get your bags off than it would take you to take them out of the overhead. Oh, and it is a big deal waiting for those bags when: A. you have a tight connection or, B: the yellow tag didn't get put on your bag (~ every other flight this happens).
As a passenger, the E170 is excellent and I would take it anyday over a -700.
