Over an entire mana bar, assuming you're spamming every ability the instant it comes up, new Tear gets you two extra abilities on-buy (assuming we get it at 6), or one more E, or 22 HP. If you use nothing but E, it gets you 3 more Es, or 66 HP.

New Catalyst gets you 110 HP back if you use nothing but E, and no additional spell casts if the enemy doesn't poke. In order to get even one more E, you need to get hit by something that does 20 or more damage. You will get 87 HP back if you're spamming every ability as it comes up. In order to get even one more E, you will need to get hit by something that does 137.3 damage.

Assuming you're constantly at more %HP than %mana, you will get one additional cast of E when spamming every ability with Chalice, and 8 more casts of E, or 176 HP, when using nothing but E. And if your %HP ever drops below your %mana, you get Sion's level 16 health regen at level 6, or more than the Dong's level 8 health regen, getting 4.36 health back every second your %HP is lower than your %mana.

So, if we're talking purely in-lane mana sustain (such as against a tank) and not long-term power, Chalice is better. If we're talking about long-term power, Tear is better as it turns into Muramana. Though, Chalice can turn into Mikaels, which has a pretty powerful heal (150 when stacking health is crazy) AND CC REMOVAL and 10% CDR for even more abilities quickly. When against an AP heavy team and you don't think you'll need the damage from Muramana for some absurd reason, it may be theoretically better to go Chalice which turns into Mikaels because of the better mana sustain and the fact it gives the active. Heck, it'd probably be pretty good against a CC-heavy top laner for in lane, if you really needed the extra help.
