I had to try out for myself, to find out what works for me. So, the following is just that: my humble opinion.
The Cold Steel handle is oval, in fact I liked it, but it is not my top pick.
The H&B Forge uses several handle sizes, all of them are more pronounced tear-drop shaped. I did not like the feel of the largest H&B hawk handle size as much as that of the Cold Steel's one.
The medium H&B Forge handle and the Fort Turner largest handle sizes are practically the same: these are the ones I like the most from the 3 mentioned.
Beside the size, it is important how well is the handle finished and what kind of coating/lacquer is applied..
The Fort Turner handle surfaces are among my favourites, however I've read that other people find them too slick and prefer the rougher H&B surface.
The Cold Steel handles are coated with some kind of varnish, which I preferred over the slightly sticky linseed oil soaked H&B surface.
My absolute favourite however is the handle on the hawk assembled, heat treated and sharpened by Ragnar. He applies a finish which has some pine pitch and/or tar in it and results in a very warm, smooth surface feeling. :thumbup:
