You can do it either way. Look at the card page for the cards to see the difference in stats.

Note that you cannot get any more Whimsical Tempest Queens, so it is only possible to get the highest evolution of [Hurricane] by adding [Breeze] to the evolved version. Not enough [Breeze] cards were given out for people to evolve two [Gust] cards, two [Squall] cards, etc. Also, these are not tradeable so you cannot trade for more.
