Best Quests

Calling all completionists and lore hunters. I'm looking for memorable quest recommendations. There are hundreds of quests in the game and I'm hoping those who have done them might remember which ones stood out to them. It's basically new content to me since I never really paid much attention to them beyond the ones with big rewards, and I'm hoping there are some hidden gems out there. Thanks.

My favourite quest in the entire game - Three Men and a Closet. About as bonkers as you are imagining right now.

Pretty well known series of quests, but the Saga of the Skyserpent in Aht Urghan is also a favourite of mine.

Sleeping Beauty (healing herbs).

Get the Picture is a good one that springs to mind immediately. But I think my all time favorite is one that I would've missed completely if I wasn't going for Mastery Rank: Babban Ny Mheillea.

You only have to do one of the nation quest lines in the WotG mission/quest storyline, but all three are good. San d'Oria is a little more bland to me (but still solid), but I found Windy and Bastok excellent.

Great suggestions already, thank you. I think I might go town by town and post any that stand out.

Hat in Hand
Was one of the first quests I ever did
When you asked for a memorable quest this is instantly what comes to mind
FFXI being my first MMO and not using wikis yet
I had no idea what talking to people meant
I didn't know if I needed to talk to real people I didn't know if I needed to /tell NPCs I couldn't even tell the difference in NPC and players yet

You get a not so good but cool Windshear hat
I thought elemental resistance meant so many more things than it really does

It was a lot of fun learning how the quest works, getting to see and speak to all the NPCs in the zone
Then getting a new rare ex hat to wear

Another memorable quest:
All the star onion brigade quest line

"Beast from the East"
Everything involving Areuhat is great.

I loved this quest back in the CoP days. To do it requires going out of your way in Riverne, and provides if I recall correctly some lore about the site via a CS.

A Bitter Past from Tavnazian Safehold always stuck with me.

Starting NPC is Frescheque. A sorrowful small tale with a little bit of hope rekindled at the end of it.

A Timely Visit is... well, it's something else.
I highly recommend doing it.

Gift of Light is the only one I remember because it uses a mini game that, even though not very exciting, is afaik the only time used in the game.
Since it's probably not the most efficient way to gain Abyssea - La Theine fame I think I only did it once or twice till I succeeded and then never had to do it again.

Means someone took the time to create this mini game without the intention to squeeze every last bit of "game time" out of it and I respect that.

Oh the bungee game, yeah that was something.
