Depends on how you drive and whether it still has any warranty left! The DH package adds a fair amount of new hardware, a lot of it will not be inexpensive to repair when it needs work.
From a handling viewpoint, personally, I've not driven one with it, so only know what I've been told. It does corner flatter, but I'm not sure you'll actually get higher G's with it. May end up with lower impact over a bump, but again, can't say for sure.
