There are some in my company who do not use speed brakes as they plan their decent to be at 2000ft AAL for about 20 track miles. I never thought about it like that before, but I guess they must be very good pilots!!
Speed brakes are there to be used as required. To dogmatically not use them may then mean you are using flaps as speed brakes which Boeing recommends against. (Don't know about the bus)
Not many descents in the airspace I use seem to go as planned. I do not like using the speedbrake, but use it as required.
