If we are being serious then Mars is the only real planetary option at the moment.
As a hypothetical idea using the Sol system (ie we ignore that the gas giants atmospheres/temperatures would all kill us and that if they didn't kill us we wouldn't be able to see anything through them anyway) then I agree with Euphoria, Saturn is probably pretty neat visually if we could stand on the outer surface.
