If you gave us an approximate location and size required then someone can make suggestions for your needs. I would say get The Ax Book and read the three chapters on The Right Ax, The Efficient Ax, and The Double-Bitted Ax. I think those are the right chapter titles.
If you are unhappy with the Gransfors then you are probably looking for the very best. This basically means that you will need to get a vintage axe in unused or nearly unused condition, grind it, and cut your own haft. This is not an easy task and I speak from experience as I started out with Gransfors axes. They come razor sharp and aligned properly so there is no work involved. All you have to do is learn to properly use and maintain the axe, which is not to say that is easy, but is only about half the knowledge required. Haft-making and filing require a lot of learning as well. There are benefits to starting this way as you only have to focus on axe use. But on the other hand you are delaying the learning involved in fixing up axes.
You could also purchase a House Handle and slim it down. This depends on your experience though, as a thicker handle can be better when you are learning and making mistakes.
You want to look for good blade geometry, it is almost always better in a double-bit than a single, but the double is more dangerous. I think Maine patterns and other similar patterns are best, but this could be different for your location due to the difference in trees. You want something in the range of 2.5 to 3.25 pounds if you're a beginner with a 26-28" handle (forest axes are fine as well). There's not much else to look for other than what was listed above. I left out axial rotation, but it is basically the balance point on the axe. For a single-bit it is approximately the distance between 1/4" within the eye to the edge. A shorter distance means a more accurate axe.
You also have to check how open the axe is, where the edge balances. It should rest between the middle point of the edge and halfway between the toe and heel. Check by laying the axe edge straight down on a flat surface with the end of the handle resting on the same plane. And check for grain runout too.
Preference goes to sapwood handles, straight handles or handles with only a minor curve, and the most uniform looking head. Check the sound of the steel and hardness if possible.
Apart from what's in the article and what I listed here I can't really think of anything else in selecting an axe.
