Sacred Defender is to defensive and not enough DPS or even burst DPS
Divine Might and Sacred Stance Strength not stacking is just wrong
Sacred Defender Capstone is not desirable over Weapons of Good (Did you not listen when people complained about Divine Intervention when it first came out). Paladins are already hard to kill, we don' need an Enhancement version of the Die hard Feat.
currently the best option for me is 39/41 SC/KotC and I'm still not happy with it as I lose saves, ac and prr just to maintain some DPS.
