As others have said, you are really wasting your time, and potentially money down the road due to excess fuel consumption, until you add up the loads in your home and figure out your needs.
For me, I divided loads into Critical (must have), Nice to have, and luxury items.
Critical loads consist of HVAC (wife has severe asthma and heat/humidity and cold air set her off), well pump (water and toilets), fridge, garage fridge, and freezer (prevent food spoilage).
Nice to have includes lights in living room and master bedroom, TV, cable modem, router (useful for knowing what's going on with storms, hurricanes, etc). Stove is dual fuel (gas cooktop, electric oven) so the cooktop needs very little power to operate. But I also have a large 3 burner propane camp stove (runs off 20# bottle), 36" Blackstone propane griddle, and a couple of Big Green Eggs so I have plenty of cooking options.
Luxury items that aren't powered are the hot tub, the electric dryer, and the electric oven in the stove.
Bottom line is you need to do your research first and figure out your needs before you buy too big or too small of a generator. If you aren't willing to do that, there are plenty of electricians out there that will do the legwork for you, at a price of course.
