In my opinion, the F-4G HARM capability was pretty close to that in the Growler. The earlier CJ tactics I heard briefed reminded me of the limited F-4C Weasel, which involved a lot of missile launches against targets that weren't even there. Kind of like launching an AAMRAM into empty airspace because Intel reported a Mig was there 3 days ago.
I do love the basic F-16 though. Incredible aircraft. Better visibility out of the back seat than the front seat of an F-4. Easy to fly, but like every other fighter, very challenging to employ correctly.
