When comparing the E2-Series with the A220/CSeries, saying that the latter is the better aircraft is maybe a bit like saying that a Mercedes is better than a Ford. The Dash 8-400 is also a better aircraft than the ATR72, yet the latter outsells the former by a big margin. The E-Series was built to be cheap (and lightweight) and that shows everywhere around the aircraft. Embraer/Boeing Brazil will probably have to sell it cheaper than Airbus but with a Brazil production line it can probably do so still turning a profit as labor will be cheaper than in Quebec or the US.
