Having flown almost every type of military aircraft made since the P-51 Mustang (and it's nemesis, the Mitsubishi Zero) I can easily report that the F-4 Phantom ll is the most versatile and longest serving military jet ever made in the following categories: Best Fighter, Best Fighter/Bomber and Best Interceptor on the planet.
This aircraft did it ALL folks! It could be configured to any standard and was so far ahead of it's time, that some versions continued to fly until the late 90's. It was engineered in the early 60's.
My favorite version is the F-4G (Germany) with Canadian engines, which far over-powered anything on the planet at that time (the SR-71 could fly much faster, but took awhile to get past 4000 mph. Also, for you SR-71 speed freaks, the SR-71 could not handle, it was made to fly straight and fast only).
Not that it was ever made public, but the F-4G version could fly at up to 4000 miles per hour for short periods. I once raced a much newer (by some 20 years) Soviet Blackjack bomber, over water near beautiful South Africa and kept pace with it until it cleared South African airspace. The wings glowed red afterwards (I'm not kidding) and I was ordered to fly at much lower speeds for over one hour, to cool the wings, prior to landing.
All F-4s featured a unique wing and tail design, which gave it one-of-a-kind handling characteristics. Many enemy fighter pilots never 'locked-up' a Phantom during their entire career, because giving some rudder on the F-4 caused strange things to happen - as compared to other fighters. Instead of losing altitude in a turn, the F-4 gained altitude while turning and could stay in a continuous turn (at dogfight speeds - 250-550 mph) all day long! This is a great advantage in a dogfight, as at low altitudes, the competition was crashing into the ground trying to stay in the turn, in order to 'lock-on' to a Phantom.
As I mentioned previously, most F-4s were more than powerful enough, with the possible exception of J-79 'smoker' engine and the RR Spey engine variants, which were designed - not for explosive getaways, but for other purposes.
This advantage - present even with a full load of ordinance! - allowed many Phantom pilots to fight their way successfully into a zone, drop their loads successfully, then protect other bombers coming into the zone successfully, or back up other fighter pilots close-by successfully, or hundreds of miles away. With such instant speed available, a dogfight starting 200 miles away, was only a few seconds travel time in the F-4!
Astounding power, weird handling, huge weapons choice, unbelievable ordinance tonnage capability (yes, I did say 'tonnage') tough enough to withstand small arms fire and other AA, long service life, easy maintenance, parts interoperabililty, nuclear capable, aircraft carrier landing capable, all-weather, every fuel tolerant - what else do you want in a fighter, fighter/bomber and interceptor?
By the way, even today some things about the F-4 Phantom ll are still classified! Sorry I can't tell you more.
