Having fiddled with spell vamp and life steal with Kayle I have to say that Life steal is much better. The AP ratio is really low and relies on you getting a lot of AP to make it anything close to the sort of sustain Life steal can get you by mid game assuming you buy an AD item aside from the Life Steal item and any one of the attack speed items that Kayle enjoys using.

The Q spell vamps well however and being single target you get the full effect but if you want to sustain yourself with E you're gonna want Life steal. Sometimes Spell vamp works on units with nice bursty AP ratios but Kayle's E is a whittler tool. The passive makes your rightous fury auto attacks more valuable but they aren't strong in and of themselves.
