I've never done portraits but to me, they are like fretwork where you are constantly moving your saw blade from one hole to the next. If that is the case, the Pegas would be far faster and easier to work with. I know that Scrappile does a lot of fretwork on his saws but I'm not sure which one he uses primarily for fretwork. He has a Hegner and a Seyco. Maybe he'll answer on here when he sees this topic. For my 2 cents worth, I'd go with the Pegas. Price and ease of use would be my deciding points. But like I said, you have worked with the Hegner for many years so you are used to how it operates.
