Your comparison with shielding smite leaves out a few crucial differences.
* Displacement is an immediate action, which means the wizard can throw something beefy in the same round- say scorching burst or magic missile. Thus, the fact that displacement doesn't have a damage component is somewhat immaterial- the wizard can complement it with a damaging attack.
Like I said, they are not directly comparable. However, Shield Smite gives a defense without using up an immediate action, hence, allowing the Paladin to still use an immediate action in that round.
Shielding Smite is like using up an attack action plus gaining defensive benefits without using up an Immediate action to gain the defensive benefits.
Puggins said:
* Displacement will always activate, while Shielding smite does nothing if the paladin misses the attack.
Not necessarily true. The Effect portion of Shielding Smite is not in the Hit section, hence, it implies that the AC bonus always occurs.
Also, Displacement activating is not a guarantee of success. It might help, it might not, it might makes things worse. The AC bonus does not ever make things worse.
Puggins said:
* Displacement will work for any attack, while Shielding Smite only covers attacks against Armor Class.
Yes, I did mention that. Advantage Displacement.
Puggins said:
* Displacement will definitely be used at a beneficial time. Shielding Smite will go unused if the subject of the protection is not attacked. This is useful to deter attacks, probably, but if more than one target of value exists, the smite will be compromised in usefulness.
Again, not necessarily true. For a 16th level Wizard with 50 hit points, using Displacement to stop 5 points of damage might NOT be a beneficial use. Or, stopping 5 points of damage on the Fighter might not affect the combat at all. The power states that Displacement can be used after the attack roll hits, not after the effects are specified.
Plus, Shielding Smite has the advantage that it can be used as a deterent. "Protect the Wizard Paladin!".
Just like Displacement is attempted to be used at beneficial times, so would the AC bonus of Shielding Smite.
Puggins said:
* The paladin must actually make an attack for shielding smite to work at all, which brings up problems of opportunity, where the paladin cannot make an attack and thus cannot provide the protective aura- if he is slowed or immobilized, for example.
Not necessarily always true based on what we know so far. Can immediate actions be done, even if someone is immobilized?

Overall, I judge displacement to be a better power. Just how much better is a different matter- I simply have no idea, since I've played with neither. I will say that displacement does seem to be overleveled, but by how much remains to be seen.
Well yes, you skewed the information in Displacement's favor a bit before making that assessment.
We are making a bit of an apples and oranges comparison here, but the apple appears to have as many advantages as the orange. Not that the orange does not have different advantages, but not enough or powerful enough to be clearly better and significantly so. And definitely not 16th level better.
As far as we can tell, Shielding Smite grants a defensive benefit more often than Displacement. The difference between standard action and immediate action is mostly offset by the additional offensive capability of Shielding Smite. From an overall probability POV, Shielding Smite will be used more often and be effective more often.
And, that is just one example. Even if the general consensus is that Displacement is more useful than Shielding Smite, it does not mean that there are not other Per Encounter lower level powers that are as or more useful than Displacement.
