If itong dalawa lang ang pagpipilian then I would go for Lacson. Isko should have waited to become president after 2 more terms in Manila. He has a lot to do in Manila and yet he is leaving Manila to Honey Lacuna (Who is his Vice Mayor) and even abandoning his running mate when he thinks he could gain the advantage. He is showing that he would leave anyone behind in order to get to his goal. This would work for some of our Filipinos (some of them like this aspect of him)
If Isko would honestly just wait, he would have a better chance in the next election and boast a lot of what he could have done to Manila since 3 mayoral terms would be sufficient for him to push his supposedly agenda for the capital.
