I've used both and you can't wrong wrong with either one IMO.
That said, I find the seal & shine to be easier to apply. The ceramic stuff can be kind of finicky if you're not meticulous about prep work, right temperature, not in sun, etc. It has a tendency to streak for me (especially on darker cars) if not done in the right conditions, and the streaks can be difficult to get off, but time and a couple rain showers does the trick.
The seal & shine is one of the easiest I've used. Shine/gloss afterward is pretty comparable between the two, but ceramic stuff beads water about 30% longer in my experience-- personally I prefer the seal & shine due to less effort involved in the application.
