for overall experience, staring at the tree to enjoying the heat, ash, Absolutely the easiest processing wood with the hardwoods and burns dang nice. With that said, I take very few, as we *don't* have the EAB around here yet, so just letting them grow.
After that, red oak taken from inside the woods so it is straight and easy to split. Shagbark hickory is fan freeking tastic firewood, but the bark collects dirt and rocks, dulls chains constantly, and if it isn't de barked and processed pronto, attracts bugs from several state over, they absolutely love it, so you have to process fast and get the sun and air to it.
For spring and fall, tulip poplar, processes just like ash, just half the btus, which is fine to keep a fire ticking over good when you want just some warmth and it isn't real cold out. Shoulder season wood, I am burning it 95% lately, just to keep the damp out of the house. It isn't cold, but a one split at a time fire is working. Plus they get hugemongous, fast. Just fun to cut into perfect rounds.
Everything else is in there some place, I take it all, just keep the absolute primo stuff separate. If I had a huge orchard, I could get by easy with apple/cherry/peach/pearwood and no splitting needed, just branch wood and mature culls.
Some good wood here is we get winged elm and dogwoods, the elm croaks at just the right size, either burn as-is or one noodle to half it for an overnighter. All the dogwood is small, right in the stove, I love that no splitting needed wood. Burns real good, seems to be just a scosh better than oak, but not quite hickory.
Tell ya what else is good wood, orange or citrus. I rented a house with a small grove in Fla, burnt it outside, the trimmings, in the firepit. I could see it would have worked well in a stove for heat. Smells great, too.
