I don’t think it really matters as both will suffice.  I have only had my
aluminum tank for a little bit of time so no issues to complain about other
than the first tank I purchased had a very small leak in a welded corner -
I have had multiple plastic tank issues - a couple leaking fairly
significantly but I was not too far from home.

I would go with GW given the sight glass but that is my preference and I
have no data to back it up.  I have heard good things about both tanks from
each vendor.
