If both items are to have life steal, I personally think they should offer the same amount - so that the reason you buy one or the other is for the secondary effect. It's the same reason all B.F. items now offer the same AD - so that the decision to get IE, BT or MS is for the unique effects (and now Essence Reaver, although it's far from competing).

And the problem with 2% mana vamp is that (a) it's calculated post-resistances (meaning attacking someone with armor causes you to restore less mana) and (b) the value you restore (even if attacking someone with 0 armor) scarecly surpasses buying actual mana regeneration. Similar to the distinction between Ancient Coin and Spellthiefs, the aggressive/risky option (on-hit) should grant more effective mana than the passive option (mp5), but currently it doesn't (until you have lots of AD and armor pen).

An alternative would simply be "Restores 2% of your maximum mana on-hit" or "Restores mana equal to X% of your attack damage (pre-armor)".
