The RTAK II seems to me to be the most like a small machete. That is a good thing in my book. The Ranger or Swamp rat might be a stronger knife but I am not sure how much strength you need.
For me, I want speed and the ability to chop for hours without getting tired. A knife like the Dog Father or Ranger is going to tire me out before I am done with my cutting and chopping. They are also not good for fine work or light veg. They are like axes with an inline handle. IMHO, there is not much use for them.
The Trailmaster is still a good knife. I think the RTAK has the edge though.
