The amsmath "alignment building blocks" gathered, aligned and alignedat (amsldoc.pdf §3.7) are probably doing smart things that array doesn't, like making sure "=" just after an "&" is added proper spacing for a relation on either side; with array that would require "& \mbox{} =" I think.

So I'd recommend against array for anything else than a matrix, and use of aligned or alignedat instead.
