Blancpain made few watches with both a Tourbillon and a Carrousel. Thanks to the link below, the brand explains the difference between these two complications.

Among the three UN timepieces you showed, my preference goes to the Freak which is really, in my opinion, an unusual timepiece that you won’t find anywhere else. I’m less thrilled by the two other models. But, of course, it’s just my personal feeling and opinion.
Hope that helps.
