Proof of the puddings is if someone takes a dump in the forward bog the flight deck doesn't know about it. Ejets you get the full flavour and sound effects in the cockpit.
They are both engineered the same way. The only difference is the number of fans used. The Ejet has 3 per bay/bog. The CSeries has one for both bays with a backup.
I know both types intimately.
