Are all cloning gels created equal?

[JerBear]

I searched for a cloning gel specific thread but didn’t have any luck and apologize if I missed it somehow. So the question is, as long as a cloning gel brand contains the main component of “IBA”, are they all equally as good? As a broke “sumbitch” I’m trying to justify the $50+ price for a small container of Clonex gel over a $15 similarly sized unknown brand.
