Classes for soloing u8+

So, what do you guys think that is the best class for u8 and u9 solo? i've been using Candy Barbarian to solo u8, i almost don't have to use potions, i use them only to kill faster, its doing well but i think it could be faster, i was thinking about either going Neon Ninja or Gunslinger(heard it is the most dps class endgame) or Lunar Lancer, but the current pearl price is just too much to waste on something bad,so,what class are you playing on what uber and hows it?(if possible add the stats youre using for items/gems)
