If you live in a very humid climate, like a jungle environment, horn is a very nice material, as horn thrives in humidity. The whole reason the horn cracks is because it dries out, but in da jungle wid da mankeys horn is wonderful, and highly durable. However, if you are like many of us, and do not live in a jungle. But instead live in a dry, sometimes cold (cold leading to heaters leading to even drier) area, then horn needs slightly more maintenance. Though, wood will also possibly suffer cracking with extreme dryness. Anyways, another advantage of horn is that it loves to be used. The oils in you hand is actually very nutritious for horn, and helps it last longer. There is no better maintenance of horn than to use it on a daily basis. Anyways, since horn is porous, while it does seem like it should be slicker. I find that when your hand starts a sweating, the horn actually starts drinking up that sweat, saying thank you for feeding me.
Anyways, if you do live in a jungle environment, wood has the dis-advantage of suffering from potential mold/fungus. Ive seen many rotted out wood hilts, which is why horn is so popular in jungle areas, as it is more mold/fungus resistent in humid climates. But again, if youre like many of us, and do not live in da jungle, that shouldnt be a problem.
Anyways, I have a good split. 3 wood 4 horn Love em each individually. All have thier place. Like Rusty said, its something thats gonna vary more piece by piece, rather than something you can generalize. Though if you suffer from HIKV, horn wood there all good.
