I picked up the TH when my STM was having problems. Now I've got all the problems worked out and I personally prefer the streamliner. It has a little more give and a prettier top end to my ears. The Aggie is more mid heavy. Aguilar got it right when they called this one a hammer. It hits like solid iron. I'll resurrect a comparison I made in another thread:
