Different Planes

Hi guys. So i was wondering what is main difference between Boeing 737-700 BGW and Airbus Industrie A319-100 light is it just the matter of taste or is one better than another one in cost efficiency? As all the data for both planes are pretty much the same. Also same goes for Bombardier CRJ 1000 NextGen EL and Embraer 190 and Sukhoi Superjet 100-95. So should I just take the one I like or there actually is something that i should consider before getting any of these planes?

the fact that 90% of all players prefer 737BGW over A319 and Dash and EMB over CRJ and co might tell you, there is something…

a search on the board would do the same… in about a thousand threads…

use the aircraft type evaluation tool in game and you will see the difference.
