Mostly maple here with some ash, beech, yellow birch, and occasionally oak mixed in. I prefer the rock maple over the softer maple because it burns a lot longer. Right up there with ironwood, dense stuff. Fill the stove at night and forget it.
White birch is nice for the fireplace, smells good and makes purty green flames when the bark burns. Just doesn't last long.
I avoid softwoods like pine or hemlock because of the creosote problems. The last thing you want on a cold Janurary night (or any night, for that matter) is a chimney fire.
