No bro.
For every one he scores, he misses like 15 (and even hits the wall or shoots it over the bar) with few even troubling the keeper.
I'd be eager to look at actual stats on amount of freekicks attempted and ones scored by Ronaldo, it must be quite low and not worthy of being mentioned with the world's best in this attribute.
I think there are 2 reasons why over-rate him in this regard.
1) His fame. The same reason, Beckham although a great FK taker is NOT as great as most think he is at it.
2) The BEAUTY of the rare ones he DOES score! Ronaldo misses FK after FK but when he does bend one in, it's GORGEOUS and everybody will remember that goal for some time in their memory! Because he hits them with such power and the ball takes such a weird bend that it's a nice mixture of power + precision and technique and makes for a wonderful goal. I think that stays in heads longer than your average FK goal and helps paint an image of him as an efficient FK taker which I don't think he is.
In fact, him and Messi can improve THIS area of their game quite a LOT still in my opinion. There's definitely room for much improvement.

Pirlo definitely for me out of those last 3 mentioned.
