One of my biggest gripes with that engine is that you have to use Worldcraft or Quark for building interior structures; such special purpose level editing tools work very well for certain purposes but not at all for other purposes.
One of the biggest upsides (to me) is that Torque is cross platform, so you can compile your game for Windows and Mac.
