"Worth it" is quite subjective. There are functional improvements, and of course it uses the new touchscreen interface, but it's an expensive upgrade. The best advice is to go to a music store and try one out, keeping in mind what you will use it for.
Personally, I consider Genos - and T5 before it - to be a "premium" product where a certain amount of the price - 25% or more - is charged "just because they can" for the privilege of owning the top model.
If you really want it, and can comfortably afford it, then go for it. In those circumstances, I don't think you would have any regrets. I certainly don't.
But if you would struggle to afford it you may not find it worth it.
