Some of the Quests I love ... :
In Brocken Valley :
Saving the Bacon (humour)
A Private Delivery (the ways this quest can be solved)
The Greater Hunter (funny!)
Method or Madness (so so funny)
On Sentinel Island :
From Soup to Nuts (very funny NPC !!)
The Old Ghost and the Sea (very great and funny !)
High Hall (Orobas Fj.) :
The Runes of Wrath (interesting and funny)
Divine Descendant (funny NPC, etc ... !)
Orobas Fjords :
Reaping the Seeds (great & humourous quest !!)
Sight For Sore Eyes (nice and lovely)
Much Ado About Goblins (super funny NPC, etc..)
And many more I can't remember exactly
Most of them I love because of the humour, the NPC's character (and humour) and HOW the Quests can be solved (also in different ways via Mindreading or take other actions) !
(SPOILERS POSSIBLE)
