Agreed, just depends on what you want to accomplish. Downside to whole house power is drastically higher fuel consumption and noise. Upside to the inverter generator is you can throw it in the truck and take it to the track/trail/neighbors etc. if you ever need to run a saw/compressor/fridge somewhere besides your house.
5 gallons of fuel can't run a full size gen all day if you had to leave it unattended. An inverter with a storage tank will. Just the suck part of a 3600rpm genset.
