6% spell vamp on Quints is far better than 15 ability power when it comes to spell vamp. Even assuming you have Rabaddon's (+30% AP passive) and 4 points in the archmage mastery (+5% AP), that 15 ability power only stretches to 20 end game, which is an extra 4 damage on each tick of Tormented Soil. The spell vamp on the extra 4 damage of each tick would pale in comparison to the 6% spell vamp on the total damage (base and bonus) of Tormented Soil by the time you had a Rabaddon's. If you want a little more damage and shield strength, AP is the way to go, but you'd have better sustain with the 6% spell vamp.
