No one else has answered your very sensible question, so I'll try, from my limited knowledge.
The draw backs of riding a horse overbent:
It is easy to tip them onto the forehand.
If you do it too much, it can be difficult to get them out of it in a competition.
The pros:
It's difficult for a horse to lock its back or neck when overbent, so it can be a good way to keep the horse loose.
It's more difficult for a boisterous horse to do any serious aerial acrobatics if kept overbent, so can be used to achieve submission, or at least control.
For me, I would choose overbent over a poking nose and set mouth and neck
But these aren't the only two options surely? What about slightly in front of vertical versus slightly behind? Or nose poking but still moving forwards with a mobilised jaw?
