Both the options you're considering are really nice grills. The specs on Blaze are great but there isn't a lot of information on them outside of BBQ Guys and the related websites and Blaze is their house brand so I wouldn't consider what's there free from bias. I really like the Napoleon. I've been happy with my Weber Genesis but I don't think I'd spend the kind of money that the Summit costs on one. I think Napoleon is a better option at the higher end. Even further down in the market, I'm not thrilled with the second generation Genesis grills and would probably go with Broil King, Blaze or Napoleon.
A Napoleon Prestige 500RSIB is what is drawing my eye currently.
