I will vote for Tai Lung due to the nerve-attack, that can KO Goku for a bit, allowing him to get the win. But, yeah, this is not an easy fight for Tai Lung because Goku is sliiiightly stronger physically, and Tai Lung will have a hard time fightning an opponent firing energy (The Kamehameha) at him (That is rare in Kung Fu Panda if you ask btw, only a few people can shoot energy).
"Tai Lung is more skilled and ruthless, and I don't recall Goku playing the range game by this point yet, despite having the Power Pole and Nimbus Cloud. Probably Tai Lung for now"
I'd like to note that Goku with the Power Pole almost always opens with wacking stuff with it in-battle. So saying he doesn't play the range game even though his first opening move is to smack someone in the face with his power pole is kind of untrue.
Yes, he should be as effective with pressure points as Master Shifu, and he only lost against Master Oogway because he was a far greater master at the application of pressure points than anyone else at the time, including Tai Lung.
