Arai helmet purchase: Is the RX-Q worth $60 over the Vector-2 ?

[TT C6]

I am looking to to replace my 7 year old Arai RX-7 Corsair.

I was gonna purchase a "budget" helmet and was set on the new fiberglass AGV K-4 for $220.

Although Arai's pricing seems ridiculously high, I keep getting pulled back to them.
So, I've narrowed it down to the RX-Q and the Vector-2.

So, is the RX-8 worth an extra $60 over the Vector-2? Why?

Thanks.
