Since stating which vehicle is “good” will vary wildly from player to player, I’ll say that the F-14B is a lot like the F-16’s in the sense that there’s a mixed bag of strong traits and very weak traits the aircraft has.
Pros:
Large missile playload, if you subscribe to the idea that # of missiles is important, then it’s a big plus.
Large number of countermeasures if you take the flare pods with the 9L sacreficing the extra Aim 7Ls, on paper you’re effectively never going to die to IR even if you take mixed countermeasures.
It’s got solid flight performance all round, maybe not as good as a mig 29 in a sustained dogfight, but still better than most stuff you’ll be seeing.
Lots of radar modes and a very long search distance, I personally don’t see the use in this, but you have it.
Cons:
You’re heavy, and therefore don’t have the greatest acceleration in the world, so try to keep your speed.
The radar can be painful because it only has look-down in front aspect, so don’t be expecting to lock things from the side or rear in about 90% of cases, sometimes causes Sparrows to lose lock in mostly front aspect if the enemy is at your alt or below.
The wings will sometimes decide to spontaneously break, doesn’t happen often, but sometimes at even sub mach speeds in a straight line, the wings will fall off, likely a bug in the code, but still a problem.
Bugs, this vehicle has a ton of tech, so it’s much more susceptible to systems working incorrectly than any of the other top jets, bugs, or if a system has had cumulative nerfs, it might behave weirdly. If you want to play a lot of this jet at top tier, just accept that something will not be functioning properly at any given time.
