The E-170 series has a range of 2,000NM with RSVs for the STD version. The Mmo is the same for both models. As far as fuel burn, I could not find any data on the CRJ-900, but if memory serves me correctly, having sat up front on each, the burns are similar.

As far as not being able to notice the difference in the cabin? I will have to disagree with you there. I used to commute on RAH's 175's every week, and they are WAY more comfortable than the CRJ series. They even have bigger seats and more pitch than the US 737s.
