Less versatile, less payload (a-g and a-a), less range then an F-4. This was the nAvy version of the F-104 and might have been the better F-104 to many NATO countries but it was not the better F-4.

A stealthy theatre bomber would surely be an great asset for Russia.

No, it is correct in any conflict. More time on station is becoming increasingly important as you need less weapons to destroy a target. In the past a flight of 2 dighers would come to the front attack a target assigned by a FAC, drop their load and head home. Today they would come to the front, hit the first target with a bommb, then attack the second, third, fourth, or more target.

Is it not silly to compare F-22 and EF, as historical they were not competitors but were meant to supplement each other. Both were designed to win against SU-27/MiG-29 (and upgrades) in a cold war setting. The F-22 was meant to open the way for strikes made by F-117 and other low observable bombers, EF was meant to keep the Russians out of NATO airspace.

There is one thing that is so often overlooked in forum discussions, but has shown to be off great importance in all current conflicts and that it is time on station. You can pre-plan strieks against strategic targets and you can switch to cruise missiles in may cases, so that low RCS in not need in any scenario. But you can not replace endurance when it comes to flying CAPs and CAS. If the smaller fighter can stay 30 minutes on station and the larger is able to stay 45, ejile carrying equal bomb loads and assuming that fighters operate in pairs. You will need 96 sorties of the smaller aircraft a day but only 64 for the larger aircraft.

Again that depends. If the SH got a newer version of AMRAAM + AIM-9X then it might win against a EF with an older AMRAAM version and AIM-9L/M.

If you give the equal weapons, then I believe EF would win most of the time.

That is another untested theory. Airfield repair has become quick, you can easily operate from many civil airports and airfields. Quite a lot to hit with a cruise missile attack, when the attacker is not the US.
