Probably the best jet was the Meteor, but I voted the Ar234 as it's my favourite. I feel that they were in a class of their own, and it had terrific potential for further development. Like all German jets it suffered from Hitler's pre-occupation with bombers, bombers, bombers - It was a wicked 'Blitzschnell' bomber at that time of the War, but the old ' too little, too late ' doomed it's true development potential. I would have liked to have seen some serious forward-firing armament on them and improvement on their low-altitude performance, but they were excellent high-altitude reconnaissance aircraft and bomber- [only a 1000kg.]. They also may have been a handful for the Mosquitos too, if they'd had forward-firing guns [only 2x 30mm rear-firing installed], although not as manoevrable. They were IMHO the most well-developed and potentially reliable jet in the Luftwaffe, but by that stage of the War the factory workmanship was deteriorating beyond redemption...
