Just to add my view as Embraer flyer, but on a different airline - Air Dolomiti - much tighter seat pitch and exit row is really the only pleasant seating option. Very notable difference to BACF! Advantage: in C/J, you have two seats (as across the LH group). Another difference (as already pointed out): 3 instead of 2 flight attendants....Given that BACF is planning for 3 flight attendants, it is clear that they are not planning to go to the 'empty-seat-next-to-you' approach in C/J. EN doesn't mind having three, as they have enormous pricing power in Northern Italy.....
