Maybe I'm missing something here, but to me those are regular (albeit exceptionally good) fellatio/blowjob videos. What aspect of them makes them "vacuum fellatio"?

And about the question, I'm not a big fan, usually like the woman to go all in with her mouth~
Agreed. Using one's hand to jerk someone off while sucking their dick used to be known as a "cheater's blowjob" because it is taking a shortcut and is usually a mark of either inexperience, lack of commitment, or incompetence.
