Well the German ME 262 was the first jet powered plane to fight in WW2. Its top speed of 560 mph and ceiling of over 37,000 feet made it hard for most prop planes to target the jets in a high speed fight. The Spitfire had a top speed of 380 and 35,000 feet. This made it easy for a jet to drop in from above and take out a spitfire in formation and climb back above the Spitfire's top fight area. That being said the Spitfire had a greater turning radius especially in low speed flight against the Me 262. The ME 262's engines had low thrust at low speeds and a wider turn radius. If you look at the timeline of the war Germany had lost most of their experienced pilots by the time the Me 262 was ready for deployment. Factoring that in with pilots using traditional propeller based dogfighting skills while flying jets might have actually negated the advantages of such a fast plane. Also Britain built the Gloster Meteor jet and it was put into service in July of 44. The main aircraft that the Spitfire faced in combat were the Bf-109, Bf-110, Heinkel He-110 bomber, Junkers Ju-87, Ju-88 bombers and the Focke-Wulf Fw 190. So I guess I'm saying that the Me 262 was a better aircraft than the Spitfire in some areas but not as good in others. In lots of fighters of that day it all came down to the skill of the pilots.
