I think XC7 broke it down well. I am a Bighorn guy and have been running them for years. Between the 2 you listed, I would go TL3 for sure. If you're looking to save some cash the Bighorn Origin is a good option. It does everything the TL3 does, but they are made from chromoly rather than stainless. Chromoly is actual a little smoother. I would definitely pick and Origin over a Stiller action if it was my money. The pre-TL2/TL3 actions were chromoly and are still outstanding.
