This one, for me, feels like a bit of a no-brainer. Tirion Fordring's "In Dreams" questline is incredible!
https://classic.wowhead.com/quest=5944/in-dreams - The rewards are fantastic, but that's irrelevant. It's just a fun chain that ends with a great series of fights.
Second has to be the UBRS key chain. Always enjoyed that as well.
UBRS key feels super valuable. Having that attunement feels valuable for the entire duration of Classic. Not many people know that the https://classic.wowhead.com/item=12344/seal-of-ascension actually has a functional purpose outside of opening the door and can be used during the rend encounter:
"At some point during the battle with the false warchief, Rend Blackhand, you can use your Seal of Ascension to summon a shade of Vaelastrasz (looks like a ghostly red dragon), who will heal your entire group for 5000 HP as well as 'help' you in your fight against Rend." worldofwarcraftfandom.com
YES! I have bowled over so many people by summoning Vaelastraz! I don't get why it's not used every time!
The first time around, I swear I was the only one who ever used it!
The Legend of Stalvan probably.
Hands down the Legend of Zelda quest. :P
I think that https://classic.wowhead.com/quest=3628/you-are-rakhlikh-demon and its elaborate, slightly annoying, but immensely intriguing quest line is rock solid, it feels epic.
Boring answer:
I enjoy the Onyxia Attunement Questline.
Slightly less boring answer:
I like environmental storytelling, stuff that you stumble upon out there in the world. https://classic.wowhead.com/quest=624/cortellos-riddle is one such example, but unfortunately it's rather short.
Another great story is that of https://classic.wowhead.com/quest=592/saving-yenniku :)

Second this one .
The Ancient Leaf quest for Hunters. Finished it yesterday :)

Your answer is my answer. Fordring chain and UBRS attunement are A+.
Probably https://classic.wowhead.com/quest=1149/test-of-faith . Testing my lore knowledge, leap from the planks, getting book from SM, ... And debuff https://classic.wowhead.com/spell=6767/mark-of-shame is really funny! :lol:
One of the cooler questlines that I really enjoy is unfortunately not finished in the current state of the game. https://classic.wowhead.com/quest=1251/the-black-shield series ends abruptly in Thunder Bluff, leaving us without answers until patch 3.3.0.10772 with the adding of https://www.wowhead.com/quest=11204/deprecated-return-to-krog .
I don't know why, but this story really struck me as something that made this world feel alive.
As of last night, I have completed both of my favorites and will start on a couple of these others. I knocked out Test of Faith and received no Mark of Shame, but I've never heard of The Black Shield.
I love hidden/ unofficial quests like building the mallet of zf. It's not technically a quest but it may as well be, and it's something you would never know about your first time playing through the game unless you stumble into it by chance. I think that kind of stuff is awesome.
