When it comes to the 700 vs the the 170, I heard that the 170 takes the cake and of course the 190 tosses the 900 to the curb. But I haven't been on either of the EMBs so I can't personally speak from experience. The 170s and the 190s do look like baby 73s though. Kind of neat really that EMB took another step into making a "new" aircraft rather than the Canadian route in to just taking it to a limousine chop shop to add a few more seats.
