It doesn't matter what you use, this isn't the 90's. Pro Tools can go "F" itself for all I care. Software and technology in general has advanced so much that it really doesn't matter what you use. These days you purchase because of workflow and how comfortable you feel with it. They all do the same thing.
Just like cars. They all get you from point A to point B, but some are fancier and have features that are unique to them. It's up to you to decide what you're willing to pay for and which features are important to you.
But honestly, they're all the same in the end.
Donít worry about people stealing an idea. If itís original, you will have to ram it down their throats.
