Depends on the bone, depends on the wood, depends on the pattern. I like them all plus a dash of horn,stag,acrylic,delrin I steer clear of Cell frankly as it can be destructive (some lovely renderings with it though).
Some people have talked of dropping bone handled knives-happened to me and it's monstrous- but I think a durability aspect of bone v wood should be considered too. Bone can be prone to centre pin cracking on the spring side, very frustrating. It's likely from the pin being overwhacked and it cracking fast or a stress fracture from the spring. Never seen this on wood mind. Ebony is a rich and wonderful wood, seems remarkably durable, ages well indeed and as a worry stone my GEC 68 is breathtakingly smooth. Eyes closed you can't feel any sharp bolsters, raised/sunk pins, proud shield, it's VERY relaxing. Looks a treat too.
But then again, some jigged or smooth bone brings other delights. More evidence of the beauty of Traditionals, they look and feel just wonderful.
