stabil gas treatment vs seafoam for storage

Since I only use my Honda 2000 for emergency power during power outages: I want it to start easily, not require a lot of unneeded running just to be sure it will start, and in a normal year I don't use much gas so price is not an object. I switched to 100LL av gas about 6 years ago. Premium price, smells like gas did in the 60s, has a storage life without additives North of 3 years according to an airport manager I talked to. I drain the gas from the carb after every use and refill the tank and put it on the shelf till needed next, sometimes close to a year. Starts easily and runs smooth. I normally keep 15 gallons or so in tightly sealed jerry cans in the shed. I try to rotate at least 5 gallons a year if not in the generator I dump it in a tractor or lawnmower.

I'm also a fan of Stabil, Seafoam and Marvel Mystery, I use them all from time to time in my old cars, lawmower and tractors, most of which I use E0 fuel. A dose of MM at least once a year, Stabil before storage, Seafoam if they are sounding a little rough.
