Well, I flew both of the jets in P3D (F\A-18E and F-14B) and have mastered both of them to some degree. The Super Bug is pretty easy avionics wise. Even the complex weapons such as Harpoons, JSOWs or SLAM-ER not so hard to emplemet. They are more or less fire and forget if you don't need to mess with their program on the go. Navigation system is very pilot-friendly. And yes, I know I am talking about Super Hornet, but dont think the Hornet will be to musch different.
The Cat's procedures are very different and are taking much more time (because where is much less automated systems, in hornet you just press AUTO BIT), employing its A-to-A weapons is not harder then in F\A-18 and if you already know how to employ AIM-120 it will be easy to learn AIM-54.
But flying F-14 some times can be a pain. If you stuck in a dogfight you should be very careful about pulling the stick. No, you will not blackout, likely you will have a compressor stall, Hornet don't have such a problem. Hornet even have the Departure recovery program if you over do (home ED emplement it in some time). Well this this opinion was based on my expirience, and I hope that ED and HB will make much more accurate modules.
