Best "Divine" weapon choices at 12 str / 12 dex?

I haven't done a DS playthrough in a few years, and thought I'd try one based around the Tin Darkmoon Catalyst (which I've never done before). Just felt like mixing a bit of magic and faith together. Even though I'm not sticking to any "meta" level (not capping myself), for the first while I thought I'd try to stay 12/12. So, for weapons, would a divine mace or divine longsword be the best bets for infused weapons?

Or would a couple of points into dex or strength be better so I can use a BSS or Clay? I don't normally go to the bother of buffing, especially with bosses...I nuke them from orbit, just to be sure :)

I take it buffing isn't much good on a weapon if I have minimum stats to use it...
