Which sail would be more likely to improve sailing performance more?
If you're looking for performance gains, then you're going to need a new(er) boat, not just a newer sail.
Given that you've got an '82, the jib is going to make more of a difference, but just putting the new jib on the same way as the old one is not going to make that much of a change.
New jibs made by Hobie Cat are shaped differently. Shorter in the foot and longer on the luff - you can rake your mast back more and still sheet in the jib. Whether you can take advantage of that depends on whether you have low-profile blocks (main and jib) and shorter shrouds.
Unless the sails are damaged beyond repair, new sails on an old boat is like lipstick on a pig. Sure looks purty - but it's still a pig.
You're better off selling the boat, taking the proceeds combined with the money you'd spend on the sails, and buying a new(er) boat. You'll get more for your money that way.
