My Roger's Rangers Spike hawk throws well--then again, I'm used to the more "classic" tomahawks and have thrown my fair share. I still can't get it to stick in a target as well as my $20-$30 hawks, but the RR has a much thicker edge than those, and my target is somewhat less than ideal.
Another thing with the RR hawk--what Oliver said holds true about the tactical hawk's ability to withstand throwing. The classic tomahawks are designed to essentially come apart when thrown. Handles are considered replacable on this style hawk. Keep this in mind, as learning to throw a hawk implies lots of hitting the target handle first, bouncing the hawk off the top of the target, and generally sending the hawk everywhere you don't want it to go until you get the hang of it. Unless you're lucky, this means you'll end up with a split handle, which happened to my RR tomahawk when my father bounced the handle off the top of my target in a dramatic spinning ricochet.
Then again, I've never dealt with the Vietnam Tactical hawks, so aside from the fact that they'd be more durable, I don't know that much about them. I'm a Cowboy Action Shooter. They don't let us use modern throwin' knives and tomahawks in our side matches.
As far as non-throwing use, the Roger's Rangers hawk will eat it up and ask for more. If you're going for casual use and looks count, most definately get the Roger's Rangers hawk.
