agree with the defense choice. as far as +5%hp go, remember that when tanking, the bulk of your hps come from heals, rather than from your initial hp pool. in a long fight, you'll be healed enought that you probably could have gone through your hp pool 10 times over, so +5%hp is actually like 0.5% extra hps that you can take in the fight. +5 Defense will reduce your damage taken by far more than the extra hps.
