Both Bale and Ronaldo don't actually have the best of success rates from free kicks. The nature of the 'knuckle ball' makes it almost as unpredictable to them as it does to the goal keeper, which is why you see so many sail high into the crowd behind. It does however make for spectacular looking free kicks when they fly in.
He also only has 1 premier league assist all season, takes more shots per game than everyone in the league except Suarez, and ranks 5th for shots per game in the whole of Europe.
How he even gets compared to the likes of Ronaldo I don't know. In the same number of appearances he's scored 24 and got 5 assists, and has been reproducing that form for years. That's a whole different league to Bale.
And don't even get me started on Messi, who's another level again in my opinion
