You get with the V1. Better battery life, no built in flash but can buy and better flash separately, GPS add-on ability if you are into that, better screen and an eye viewfinder, external mic if you are into that, better built quality, sensor cleaning, mechanical shutter option (could produce slightly better images something about blooming), better flash sync with mech shutter. Heavier and larger.

However, theoretically, there *could* be a difference, depending on the user and circumstances. For example holding a J1 at crooked arms' length to compose vs. using the V1's EVF pressed up against your face might lead to additional camera shake with the J1, even with VR. Also, there are a couple esoteric technical reasons why an image shot with the V1's mechanical shutter might have better image quality than a shot with the J1's electronic only shutter. But, again, I have never detected a difference.
Your choice between the two might best be based on the other differences between the two. I really liked the J1's extra compact size, particularly with the pancake lens, but the V1 has advantages of its own, just as higher flash sync speed (which would be even more important if you could mount a more powerful flash on the camera.)
