Ebony looks really cool. But if not taken care of properly it has a tendency to crack, which is less fun. Tonewise I don't really hear much difference either, especially on overdriven tones. I guess ebony is a rarer wood also (?) so for sake of the enviroment I prefer rosewood or maple. I alway tought that Ebony needed less care, due to the bigger density of the wood. Doubt it, ebony tends to be more prone to cracking than rosewood it seems...
