It depends, if you have a big switch and don't have generator capacity
to support your total load someone still needs to manage loads. If you
are the "expert" you need to consider how other occupants will manage
things if you aren't there.
My buddy lives in a rural area with frequent power outages. He bought a
genset with an small automatic transfer switch. We selected all of the
critical loads such as the heating system, well pump, sewage pump,
refrigeration and basic lighting and ran them into a smaller panel which
is fed by the transfer switch. The advantage of this is that his family
doesn't have to scramble when the generator stalls because loads are
managed properly and they really don't have to do anything since all of
the essential needs are covered.
No one needs to know the "secret method" to make it work.
And a good side benefit is that since no intervention is required the
system will startup on its own. So say they are away the house isn't
going to be frozen in the winter or have a refrigerator of rotten food
in the summer.
