Gnomish or Goblin Engineering?

I've been working hard on my Warlock's engineering, and am now a level 200 engineer. This means that I can specialize in either Goblin or Gnomish engineering.

From what I read, there is not really a huge difference, hence I tend to go with Gnomish, just because I am a Gnome :)

But, anyone have any specific recommendation?

Oh, and ding 43, yey :)
