Is what Nadal, Federer, Djokovic do more impressive than what Barry Bonds, Hank Aaron, Albert Pujols do?

Yeah, a more appropriate comparison would be a 100mph baseball pitch vs. 130-140mph tennis serve, because then the reaction time needed to hit both balls would be similar.Baseball pitch. People don't realize that's the ball speed BEFORE it hits the ground so it slows down a lot.
You will need to provide some clarification around the question - are you speaking about what the average person would find the hardest, and you mentioned the word "returning" in the thread title, does that mean you're saying not just hitting the tennis ball, but returning it back over the net in-bounds?
The latter is an important distinction, because that requires a lot more actions than just simply hitting a baseball.

The same clarification needed for baseball because is it just ticking the ball or actually hitting a ball fair and with decent contact?
