Mageblade is the best if you have very high APM (actions per minute) and are capable of managing a dynamic rotation. Sorcs are a bit behind, but they are significantly easier to play effectively. Only downside is that you really need to run 1 or 2 pets to pull competitive DPS. I would avoid magplar for DPS right now, but stamplar is probably the easiest rotation in the game to break 100k on the trial dummy on live.
I've never run a magplar. I do run a stamplar fairly consistently. I run the Relequen/AY combo on it, but could see how Relequen/Tzvogins would be strong. Jabs + Deadly Cloak is easy mode for keeping the AY stacks up or proccing Tzvogins.
I think stamplar is probably the easiest DPS in the game to play.
