It depends partially on whether you are more concerned about heating
or cooling, and you don't say which is your more critical application.

Assuming it's mainly heating for the basement, I'd go with the
return near the floor. If it's at the ceiling and the supplies are
also
there, you may have much of the heat staying up top. But on the
other hand, if it's all living space above that's heated too, may
not matter all that much as the warm air at the top will contribute
to heating the house too.
