Aren't those like, the same thing? I guess I pick preserves?
Jelly is fruit juice thickened with pectin, whereas preserves are fruit that was cooked down until it takes on a chunky gel form.
Jelly tastes overly sugary to me. It's like eating a sandwich made with Kool-Aid mix. I definitely prefer preserves, and they can generally be found in a larger variety of flavors.
