Okay Lees, here's a hypothetical fantasy situation for you. Easy to answer as well.
You're trapped in a room; being tied up is optional, but the point is, you can't get out. And very soon your captors (?) are going to have you tickled worse than anything you've ever experienced. All the tickling torture you've ever had and ever imagined combined and at the 10th power can't equal the severity or intensity of the tickling you're going to receive. And there's no indication that it's ever going to stop.
Since you're not getting out of this ordeal,
who would you rather have inflicting this indescribable agony?
A)
A Tickle Monster of indescribable evil
B)
A Tickling Machine of unspeakable invention
I would choose a tickling machine. It is an occasional fantasy of mine - the machine is operated/put on me by a sexy sadistic woman who then watches me go into silent laughter.....
