I haven't tried that many of the classes, but here you have my Top 5 list!
1) Mage (the coolest class ever No spec (does anyone even know what Istaron means?))
2) Necromancer (not as good as a normal mage, but hell, fun for roleplay!)
3) Monk (Haiya!)
4) Wizards Slayer (not for soloing, but the only thing that can be close to threat a wizard)
5) Kensai (rp-character)
