Air/vapor barrier question #green

My house was built in the 50's, and as is typical for homes in this area, has 1/4 drywall with a real plaster job over it. My question is is this a better/worse/same air/ vapor barrier than standard drywall, taped at seams etc. I'm asking because I'm a little concerned about trapping moisture in the wall now that I've added 5 1/4" or EPS to the exterior. Thanks.
