I ended up voting Titan? Despite not even knowing he was really a recurring summon because I've only seen him VII... and my answer of "I don't know" was inaccurate. Titan is more or less useless in VII because it doesn't damage flying creatures (which there is a surprising number of) and you get him late in the game. If I had had access to Titan like perhaps against Aps, I'd probably have voted for some other summon. Oh well...
