Recurves are center shot, so you don't have to be as picky with the arrow spine as you would with a longbow.
Longbows have less string contact on the wood, so they're generally more quiet than recurves.
Recurves are built to be shot straight wristed, which brings the arrow closer to the bow arm, and makes it easier to learn how to shoot it instinctively.
Longbows are built to be shot low wrist, which takes the arrow farther from the bow arm so it requires more practice than a recurve might. The low wrist grip also makes the grip a lot stronger, and easier to retain when you're half-frozen though.
Above all the most important thing is preference, and practice.
