Short answer: No. The CR9 is ok, but the -100, -200, and even -700 are not so good. The ERJ-135/140/145 are just as bad. In the 70 seat and under category, you can't beat the ATR's and Saab 2000 at this stage. Starting in a couple game years, the Dash 8 Q400 is very good as well. If you need jet sped, the EMB-170 should launch in a couple years and down the road gives you 70-110 seat flexibility.
