I like it all, but for different reasons.
I like running a saw, because there's nothing better than felling safely and seeing a huge tree drop withing a foot of where you aimed it... and bucking/limbing is like the enjoyable after party post 4th of July fireworks.
I like splitting, all of it with a maul, because I like the exercise and seeing the wood transformed from heavy and immovable to split and burn ready, all under my own power. Plus there's nothing quite like having your maul head bounce back off a round of red oak and seeing the round split in half.... or when you split a big round into eight pieces all without one of them falling over.
I like stacking because you get a good sense of how much you really harvested, and there's nothing like five or six nice piles of wood in various stages of seasoning all lined up ready to provide heat for you. Plus I like driving a nice 4WD tractor/wagon full of wood through deep snow and around the tough terrain here in NE.
