As for me, I would either go with Duterte and Miriam. Now, to explain why:
Duterte - He is just someone new from the presidentiables seeing that it is always Mar, Binay and such who are fighting always for the position but he has a very strong and fulfilling goal for the Philippines, to discipline the country and to get rid of the criminals around the world. For me, that is a major factor because as we all know, this is what some or even most filipinos lack and even I even lack that (let's be honest). But his approach on doing so is very questionable and some might say, immoral.
But the way he played those mind tricks with Roxas was great... Well played!
Miriam - A fan of her, check but other than that, she is very smart and combined with a strong will for change. She can also be in a way or degree rough as Duterte but she takes it in a approach calmly. The concern though for her part is health.
