Automation is way better in FL Studio. I make a sine wave with the sine wave tool in Sonar Platinum and I can't stretch it making it wider between each wave. This is horrible.
 
The curve is almost useless. Sonar Platinum lets us make only two curves. You are confined by a fast curve or a slow curve. Jeeze, even Studio One lets you make deep curves.  If I am doing dub step or something else I use FL Studio. I would like to use Sonar. Please take a look at their automation and steal it! Imitate, I don't care but something has to be done.
