Peerless vs Burnham

I have a 24 year old Burnham boiler that I need to replace in my 1700 sqft home. The home is heated with forced hot water base board heat. Currently the old Burnham does not produce enough hot water for my desire so I also have an electric water heater serving as a booster/ expandable storage.
I feel comfortable with two installers. One is offering the Peerless WBV-03 boiler (three sections tank) where he will still leave in place the Electic booster because he is not positive my hot water needs will be met with just the boiler. The second is offering the Burnham MPO115 and also, the hot water storage tank (forget the model), and out door reset with the higher speed circulators. Both are supplying a cirulator for each zone, new oil line from the tank and make-up air kits.
The Peerless estimate is $6,400 soup to nuts removing all piping, expansion tank, etc right up to the ceiling and the Burnhan estimate is $6,900 with all the extras. Seeing how I have had a Burnham for 24 years, are the Peerless worth all the extra $$$ when I can get all the extra money saving add ons for just $500 more with the Burnham?
