^IMO Lorenzo is great at covering large areas and crown work, but I think Lupanzula's frontal work is more aesthetic. Also Lupanzula is far more involved in the surgery than Lorenzo.
The main plus point about Lorenzo is that he has such a ton of videos out there about his work along with many patient posted results, you can have a good deal of confidence. Lupanzula is newer, although he has quite a big following in Spanish forums.
