I bought a duel fuel generator and only ever run propane through it. I had stockpiled about seven 30 pound tanks just in case. Then we got hit with the Fiona hurricane and my house was without power for 12 days. My tanks lasted the entire time.

I'd go into town and see long lines of people at the gas stations waiting to fill cans with gas for their generators. Places selling propane - no lines.

If you can run a generator off propane, it's the way to go.
