Guderian invented the co-ordination of every arm into service, be it infantry, artillery and air force. He also demonstrated the need for everything to be mechanized (So Patton didn't expand on anything).
He led the battles in Poland, France and early Russia. In Poland he practically carried the whole campaign on his shoulders, pushing through the north and encircling the Polish armies as he went, then capturing Brest-Litovsk ended the Poles. In France he reached the Channel first, it was he who pushed over Sedan with just armour instead of waiting for infantry which could have been the win/lose descision of that campaign. And in Russia he pushed through Smolensk and to the gates of Moscow ... the only mistake he made was at Tula. But the push he did alone after being deprived of armour that was sent to Kiev rank him alongside, if not above Rommel.
Patton had the backing of the American industry, something the German Generals could only dream of. They performed many more feats of tactical genius than Patton, in fact he didn't do any. In the Ardennes the German armies were already crushed and retreating, Patton did nothing special there. Anyone with a bit of sense knows that if German Generals had that kind of industrial backing, they'd have won every battle they entered. Throughout the war they continually out-manuevred and out-marched the Allied armies.
