Which is better for whole-home backup?

The OUKITEL BP2000 Pro. It expands to 16,384 Wh, has a sub-10 ms UPS mode, and runs a full refrigerator for about 60 hours per the maker.

Which has more power output?

The EcoFlow Delta 3 Max at 4.8 kW rated. The OUKITEL does 3,300 W continuous and 6,600 W surge.

Is the OUKITEL worth the extra over the EcoFlow?

It is actually cheaper: $849 versus $879, and it includes a 400 W solar panel. The EcoFlow costs more for higher rated output and brand familiarity.

Which battery lasts longer?

The OUKITEL states LiFePO4 cells rated for 3500+ cycles to 80%. EcoFlow does not state chemistry or cycle life for the Delta 3 Max, so the OUKITEL claim is the only one you can compare.

Can I add batteries to either one?

Only the OUKITEL. It expands from 2,048 Wh to 16,384 Wh with add-on batteries. The EcoFlow Delta 3 Max is fixed at 2,048 Wh.

Which is easier to carry camping?

The OUKITEL weighs 26 kg (about 57 lb). EcoFlow does not list a weight here, but 2 kWh units are typically in the same range, so neither is a backpacking option.
