As far as the current jet we have, it blows. It absolutely blows. Can't dogfight at all, can't turn worth a crap (190 fighting a 262 feels like a super spitfire in comparison) and the ballistics on the guns are awful.
Instead, the He162 has shorter range, a single engine, different handling (more capable of dogfighting) and less armament, but in the case of the A2 model it has MG151/20s, which would be much easier to kill P51s with than the spud guns on the 262.
The differences are day and night. It's an La7 compared to the P51D. Both have high speeds, one has better turning and better guns for easier kills, and much much shorter range.
It's as valid a request as the Meteor (probably more so) At least 2 units had He162s and there's been hints that one or two more Hitler Youth units were equipped with them, but most paperwork at this time of the war was being burned in the streets of Berlin, so records are sketchy.
I don't care what nationality it is, but it would be "fun"* to fly a more nimble jet in this game.
* = Fun not to be taken as "historically accurate," or "numerically representative of the real war" -- meant only as something worthy of spending perks on -- something this game lacks most of the time.
