I've only owned the Gransfors out of the two mentioned, but i would have no problem recommending it. It's well crafted and easy to keep sharp and lends itself to tasks from fine to heavy.
I used mine yesterday to rough shape some spoons and kuskas, and also used it to split the logs from which they were made. It was a little tiring at times when trying to do fine work, but it can still do the job. If I could grab only one cutting tool in a pinch, I'd probably put my hand on the Gransfors small forest axe.
