Not sure if this group can be more clear... If you want left seat high performance commercial jet, the closest/quickest deal is the right seat. It's not about right/wrong, it's about your life and getting your goals done.
However, to counter
speedrestriction 's remark, the upside of the 737 is that everything else you pass in your career will be a lot easier to handle. It's front seat class to the left seat, and anything else that will cross your path afterwards will only make you bored with aviation. On Airbus they installed a table to eat and watch movies. Boeing installed an in-house game called Pilot Response EICAS.
