The Water temple. 
Most original? Jabu Jabu
Best Designed? Water Temple in Oot. So devious.
Best visuals? Hyrule Castle in LTTP
For me, whenever I think about Zelda dungeons recentely it's the water temple in Twilight Princess that pops to mind.
It's both a classical Zelda dungeon and yet still a deviously designed one with lots of moving elements and yet not too annoying or too obtuse to deal with.
Also the dungeon in Skyward Sword with the time travel aspect. That was probably one of the best designed ones to me.
Visually, the death mountain in Twilight Princess stands out to me, because of the lighting and the effects, the fizzying and clanking sounds of those boots that walked up ceilings. So awesome.
Best designed: skyward sword 3rd dungeon blew my mind. It's time travel mechanic isn't super unique and the entire dungeon was this amazing contraption with so many moving parts. I would say arbiters ground in TP is next.
Best Visuals : the sky dungeons in TP. Beautiful location above the clouds, I love the look of all of it. Then you had the epic dragon fight in the rain.
Most original : snowpeak dungeon in TP, it's a mansion! What a cool idea to have the yetis home be a dungeon.
Damn, I hate the look of TPs sky dungeon. So beige and plain.
What's the arbiters ground in TP again? Is that the one where you guide the statue around?
OMG how heck did I forget Snowpeak? That's an awesome location, Zelda needs more dungeons like that.

Arbiters ground is the temple with the spinner.
Beige? It's white and green, it has a cool clean look.
Honnestly, all the Zelda dungeons kind of blur together in my mind. Some dungeons I have vague recollections of:
- the thiefs hideout in aLttP: it's a dungeon hidden under the town square statue, what's not to like?
- Deku Tree in OoT: such an amazing boss
- the water temple in SS: very cool, and the boss is an automaton.
Overall I remember most of the dungeons in OoT, although the bosses are a big part of that. They all felt so fresh and new and exciting.
Yes, loved Arbiter's Ground. It has one of the best Zelda bosses ever.
