recce FAC,
Give the GR4 a chance... when we "train train train" with them in the UK, they generally don't have a targeting pod fitted, and almost certainly don't have a ROVER capability. Therefore being far less capable and easy to work with.
That may also be true of GR9 in the UK. Without targeting pods, I would agree - GR9 is the better CAS platform. However, with a pod fitted, I think it is much more of a close call and the GR4 could surprise a lot of people in a couple of months' time... FACT!?
