All of the boilers you mention are cast iron at about the same AFUE efficiency. The only difference then is the time they last, and most last longer than people. "It was also mentioned to me along the way that Peerless isn't really a quality boiler." That is sales speak.
In addition could you give opinion on whether an outdoor module control is good/bad. One vendor recommends it, while another says it will make my boiler run constantly and not as efficient. I have no idea who to believe. I thought the outdoor module control was for efficiency...
+++ That's the old torqued concept - that another control sold by control companies is only there to make your boiler run less efficiently. That too is sales speak from a severe dummy.
A problem with single-input boilers is that when zones are closed the input stays as if all zones were open, so the boiler temperature hits the maximum shortly, which is a big waste. The outdoor reset control or System Manager control keeps that from happening to save you money from being wasted during cooling down an overheated boiler.
A good plumber can make a mediocre boiler last. A dummy can make the best boiler fail. As all a boiler does is hold water while it is heated, if it holds water for decades, it's a good boiler. The major difference is the controls on it, and there aren't that many different controls. Get the burner serviced with a combustion test kit and all should be well.
