They are both good in different ways. Drogba's goal was great because of the way it swerved and dipped over the keeper. Taylors goal was class because it was a volley and it dipped just at the right moment, although to me it looks like a hit-and-hope approach, it still was a great goal. So I don't know, it's hard to choose.
I'd have to say Drogba's, on the basis it took alot more skill to pull off and he struck the ball into the middle of the goal, rather then the predictable top corner, add to that the fantastic ball control.
