I think I'd rather be launched into the sun over Jupiter. The sun you die pretty quickly as you get closer to it. I can't imagine there's much that could stop heat once you get past Mercury. Jupiter though? Jupiter is fucking spooky. Its core is hot like any molten core, but there's no crust. You'd fall through the sky and just keep falling for hundreds of miles. You'd eventually die from the heat like you would with the sun, but you wouldn't be able to see anything. At some point all you can see is goop. It's like being underwater in the Mariana Trench, but the water is nitrogen, metallic hydrogen, and liquid silicone.
