Both Cloistered Cleric and Sacred Exorcist have their strengths. CC leaves you a caster level off, but gives you a lot of feats (devotion exchange, as afterCrescent pointed out). It also gets you turning attempts earlier than SE, which is worth thinking about. That lets you take some of the other divine feats earlier, which might be nice too.
Personally, I'd go with Cloistered Cleric, mainly because archivists have a hefty feat load, espcecially if you want to DMM.
