However powerful Kun was his was nothing compared to Vader since Anakin had the highest midi count ever. Infact it was off the scales. Kun's count was no doubt measured and they would be able o compare it. If Kun even had the second highest count they would say not even Kun had a count that high. We have not seen anakin go full out and Lucas has said that we find out why he is the chosen one. After the PT is done people will marval at Anakin's power. I also think that Anakin was more powerful than Plapatine since he beat him. Anakin was able to hide his intentions from the emperor whil standing right next to him. He then was able to take direct blast of force lightning and throw him down the shaft. This seems to show he was more powerful.
