After them, play Super.
Adventure Squad is, gameplay-wise, a slightly improved EoS, but is only available in Japanese. Fortunately, the plot isn't important in AS. You probably don't want to play this one.
Gates to Infinity has a good plot and some great ideas, but its contents and gameplay are disappointing. If you're interested in the plot, play it or watch videos or something. If you do, do it before playing Super as there are some spoilers.
