Cleric better skill to have UMD or Sense Motive

[Atalius]

Starving on skill points I ask you my paizonians if you were playing a mad (or as you all call it 'Bad') touch cleric would you take Use Magic Device or Sense Motive? I already have Perception, Knowledge Religion and Spellcraft.

Either or?

One skill will cost money but has versatility. The other may save your life and costs nothing.
