Horses for courses! If its a dark, dirty night, with a low level option available and plenty of AAR available, then the GR4 will do a job for you. Almost any other time, I'd go in the F15E. Give me a good EW suite, a couple of AMRAAMs and a great Air To Air radar. The GR4 has an antiquated cockpit, mandraulic software and short legs. What a shame the upgrade didn't improve a couple of those aspects.
