8020 vs Steel

So... I have a question for those of you who have had either or 8020 aluminum or powder coated steel stands. Which did you choose and why? I know some of the pros and cons, ie. 8020 can be spendy, steel can/will rust. I also was there for, and helped fix, when the feet on Greg Carroll's steel stand decided to fail and put the whole tank in jeopardy.. All if this is a big lead up to my (hopefully) new tank. The dims will be 12' x 3' x 2'. Big, I know.. Which is why I am thinking about metal for the stand. As some of you already know, I am a cabinet maker by trade so building with wood is right in my wheelhouse. My 15 year old 240 is on a wood stand i built with absolutely zero issues all these years in.. My real concern is the dimensions of the lumber that would be required to carry such a big tank and would I be shooting myself in the foot with wood because I would eat up space below the tank .. I am very interested in anybody's thoughts and opinions...
