How were Tendulkar and Dravid different when it came to batting technique?

[Vishwajeet]

I'm guessing this may have been discussed in CW before. In case not, just curious as to who was more technically sound of the two?

Tendulkar is regarded to be the most perfect batsman technique-wise, but in my opinion he had a tendency to punch the ball with a very strong bottom hand grip while Dravid looked more fluidic and played with soft hands.

Besides Tendulkar and Dravid, which batsman possessed the most perfect technique in your opinion?.
