I flew 737/300-400-500, than A319-320-321. I only flew the 737NG (800) as a pax. Personally I prefer the Airbus. Once I got used to it, I wouldn't change back. It's easier to operate, there is a more modern philosophy behind. In Belgium there are a lot of pilots that flew 737 and 320. I only know 1 guy who would actually prefer to go back on the 737, and a couple that are not very enthusiastic about the airbus. The rest of them like it a lot (maybe a coincidence but the 737-addicts are all pilots close to retirement).. .I found an (quite old) article (link below) that describes the difference in generation i experienced when flying it. (the article is pro-airbus but i couldn't find a more neutral one).. .<a href="http://www.flug-revue.rotor.com/FRHeft/FRH9611/FR9611b.htm" target="_blank">http://www.flug-revue.rotor.com/FRHeft/FRH9611/FR9611b.htm</a>. .Enjoy reading
