I've owned/used the two-handed heavy, the panga, and the kukri style. Honestly, the only one I like is the two-handed model, and that's only b/c I find it good for work around the yard due to the long reach.
If you aren't necessarily set on the Cold Steel, I'd recommend a Tramontina over any of the CS machetes. If you want to pick up a CS, then I'd go with the two-handed model.
