Rushlight, first I do not know a cleric that would give up a cloak of pro +5 for a cloak of chr +6. The cloak of pro +5 even costs less. I have played with a lot of high level clerics. Your saves are what keep you alive in a high level game. The high level game is filled with a large number of insta death effects. The cost of giving up +5 on saves that keep you alive for +6 on charisma is huge.
Unless a caster addresses spell resistance, immunities, and saves their spells are not worth much even if maximized. For example, a 15th level caster facing a EL 18 encounter with SR will face average SR of 28. That means only 35% of your spells will succeed. Two feats spell penetration and greater spell penetration increase effectiveness of spells to 55%. That is an increase in power of over 50%. This increase is for all spells in the encounter not just a couple.
The usefulness of turning does decrease as you level. For, the first eight levels turning is extremely useful as most undead are around you level in hd. As you go above that level A character that is built as a turner loses power over time. This feat is an attempt to restore some of that power. The feat can be used to create powerful effects that are dependent upon the opponent being vulnerable to the spell without spell resistance or immunities being in play. The character that chooses this feat in very limited in flexibility. Being very limited in flexibility means you are a one trick pony.
