Well for me it'd be Almace v Espafut, no way I'm bothering to make a Caldabolg. According to wiki Torcleaver is 60% VIT mod, and as it is not a multi-hit from what I understand attack plays a less significant role, though I'm not a melee focused player so my knowledge of melee is sometimes iffy.
I actually think even with Atma, Almace/KhandaOa2-4x would beat out Espafut in DPS, but I'd like someone to math me into a hole and tell me I'm wrong. I just see it being way more TP feed for the enemy, thus in any situation where it was actually difficult and I somehow wanted to do DPS on PLD, espafut would be the best choice. (This is obviously an imaginary situation.)
To answer your question about #hit builds on PLD though, yes, fairly easily with the Store TP GSD which is what I'm currently making just for procing and messing around as I have way more important trials to work on before I make a really great GSD.
But here's the 6 hit build for PLD/SAM using a none store tp GSD:
http://www.ffxiah.com/members/item-sets?id=198180 Aurum Cuirass being the hardest thing to obtain. (Note anything on there that doesn't have store TP is just whatever other random thing I personally would throw in there because I have or will soon get, feel free to just pay attention to the store TP pieces) Personally as a career RDM I have Tamas, so if I ever did make Espafut and want to do a 6 hit build I'd have to drop it for Rajas, if they come out with more hybrid rings maybe I'll eventually be able to let go of my inventory saver.
Ignore the Store TP values on the right, it counts Rose Strap as "In Campaign" it's 26 total store TP. In Abyssea if you're focused on DD you could potentially with 2 +20 store tp atmas drop it to a 5 hit build even, Scorpion Queen + Sun Eater or something, but it's arguable how useful that is.
