It really depends on what your are looking to do with an axe. If you are looky for a general purpose field axe then the foresters style axe, 19" handle ~2lb head, is the way to go. It is lighter, more compact, easier to use for a larger variety of cutting needs, but due to size it has limitations and you need better technique. However if you have good technique you can do a lot more work for less energy expenditure. Think of it as a scout rifle or g19, not the best tool for all things, but pretty dang good for most things. I would take that style of axe over any machete or tomahawk I have ever tried. On the other hand if, you are looking for an axe to fell a tree or split wood, then you are going to want a longer handle and a bit heavier head. I am not a fan of super heavy heads, because I think good technique trumps weight and the more mass you are using the more enery you expend. Unfortunately I can't recommend buying any axe sight unseen. It used to be Wetterling and Gransfor Brucks were good to go, but I have seen to many in recent years that were poorly hafted to do that anymore. They both still make goid axes, and last I looked Wetterling had a better orice point. I just would want to inspect it first. Most of my other experience is with old tools in the FS that where just re-hafted and sharpened as needed over the years.
As far as other brands, just do some searching. I can't remember which brand, but one had a bunch of reports of the heads breaking in half due to poor tempers. It may have been a bad batch. Look for reviews by folks who usee them though, not jjust unboxed them and swung them around a bit.
