House Minority Leader Francis Escudero got the nod from the gallery, but I reckon it was Rep. Ronaldo Zamora who made the most telling points, when he discussed the "policy points" that should govern our thinking on the impeachment cases. And yes, that was Sunday’s Inquirer editorial that he quoted from:
The majority must realize the true import of the impeachment process: It is not only the constitutionally mandated process for hearing accusations of impeachable offenses against the President. It is also the President’s main venue for putting an end to the credibility crisis she faces.
The way to do that is to throw the strongest possible case against her. If she survives a committee vote on the manifestly weaker complaint, the credibility crisis will continue to undermine her presidency. After all that trouble, the President will be right back where she started. But if she survives the stronger complaint, then she can finally put the crisis behind her.
