Well, my preferences run toward the RMJ Eagle Talon over any of the SRE models.
I'd not consider any of the tactical tomahawks to be stellar choices "out in the woods". For one thing, they are all too short. Even the Eagle Talon is only 18" long -- not big by any means.
You need to understand the purpose behind these designs and compare them to your purposes to pick the right one. The RMJ hawks are designed primarily as breaching tools -- chopping cement, glass, metal, etc, with a secondary job of breaching skulls so to speak.
The SRE hawks look designed primarily for CQB, and the fact that they are made from 1095 (rather than the 4140 ordnance steel that RMJ uses) I don't think they's hold up to chopping cement, glass or metal for long. So do you want a breaching tool or a CQB tool?
If you want a CQB tool, I'll throw out the Winkler/Sayoc hawks as another contended, but hold your breath, they cost twice what the SRE ones do. But look up EdWood7's posts here. He uses them and has used them in real CQB and swears by them.
RMJ also makes the Jenny Wren, but they won't even quote a ship time for them.
A for woods use, I'd still prefer RMJ. The deciding factor comes in when you look at them:
The RMJ Shrike 13 and Kestrel (same size as the Jackal) have a longer "neck" below the head, which will make splitting rounds larger than the cutting length of the edge easier then with the Jackal. The Eagle Talon has the same longer neck and the longer haft which yields better speed and hitting power than a shorter hawk.
Now, I suspect you like the Jackal because it looks cool. If you really like the design, you might as well buy it, and you probably will anyway, only after spending a lot of money on everything but. You can gain the skillset necessary to use the tool in the woods if that's what you want to do, you just need to spend some time with it to figure out howe it wants to be used, and adapt to it.
