As a rogue I've also got to go with Burning Rapier and Ragebringer. Sadly on this server the Ragebringer quest entails:
Quests beyond the scope of this server that I enjoyed included Fatestealer (Rogue 1.5) although the tradeskill portions were annoying, Nightshade (Rogue 2.0), Sigil Earring of Veracity (Oh no, a Luclin quest! Although I did this one way past its era, so maybe it was more fun later on than when it was current) and Grandmaster Assassin's Seal.
