The economics of the 318 are dismal to say the least, which accounts for many airlines dumping them, actually scrapping them..AKA Frontier, they remind me of Detroit's efforts in the 70's to counter Japanese cars by making scaled down versions of big heavy cars, it doesnt work! As far as regional jets go, the EMB 190-195 are up there with the best of them, the new Canadair offing will be interesting as well...
