That's not entirely accurate.
A pally's main healing comes from his constant FoL spam.
Whether you're healing 5mans or 25man raids, at least 75% of your heals are FoL.
This ring loses the 6mp5 found on the two rings you describe, but it gains (with a +18 gem) +16 healing - and most people still judge you by your +healing (sadly). Also, you gain 1% spell haste. Since since 2.4 this also reduces your global cooldown, this amounts DIRECTLY to a 1% healing increase. BAsically, you increase your "healing per second" by 1%. This allows you to spam FoL faster, and thus lessens the chance that you're forced to resort to your mana heavy - holy light (if the tank or whatever gets low).
So overall, if you are a pally using badge/kara rings (unless its the ring from prince), this is a very worthwhile upgrade for you.
Cheers
