Eh, they might be the "sexiest" planes around, but I doubt they are either the most useful or most technically advanced.
The F-22 has had a lot of problem in production and usage, and F-15s can still fly circles around them. The idea of the F-22 was nifty, but the implementation that came out of it wasn't so great. I don't blame them; the engineering challenges were enormous.
As a fighter craft, the F-35/JSF is eclipsing just about every other fighter out there.
For technical prowess, I'd give it to either the B-2 or the SR-71. The stealth, gliding ability, and weapon accuracy and effectiveness make me think that the B-2 is a better plane. The SR-71 is just freaking cool. I mean, any plane were the thing to do when a missile is fired at you, is to just accelerate, is pretty cool. Not to mention that it flew higher than most missiles could reach. Of course, that necessitated a spacesuit for the pilots.
The thing is, fighters are not really useful military aircraft anymore. The military with enough fighters and trained pilots can crush any other country's air force with a stealth bombing campaign, and the enemy will never get their fighters off the ground. The real workhorses of the air force are the fat slow bombers, the boring troop transports, and the funky looking air-refueling craft.
