I think it's the difference of information. On X-Factor people can quickly see the real states of the voting (based on last week's poll) so can make informed choices about the next poll, including tactical voting if they so choose.
If everyone on the X-factor got one chance to vote, then yes I would say that they should adopt a ranking system rather than STV.
