Jupiter. Really like its "physics", the layers of hurricanes, its red tornado. I never cared about Mars or Venus, even people fantasize about them having been life-prone in the past.
Besides, Jupiter has a satellite with water volcanos (Europa) and apparently, the consensus says that if there is life elsewhere in the Solar System, then it's the first place to check, because it has liquid water and conditions similar to our Earth's abysses :)
Do you believe in extraterrestrial life somewhere in the Universe? (Other than Earth lol)
