Please excuse the empty, half empty and dirty bottles. As you can see, I love to clean my brushes!
I would categorize my brush cleaners into 2:
1) Quick Cleaner for in between makeup applications.
2) Deep Clean every once in a while.
The MAC and Clinique ones work and even look similarly. For both I spray it only the brush and use a paper towel or kleenex to and wipe the brush clean. These seem to wash off most of the product on the brush and you have to leave them a bit of time to dry before using them again. I tend to slightly favor the Clinque over MAC because it seems to be more potent in it's cleaning power. Maybe the formula is more concentrated.
Cinema Secrets dries very quickly after spraying the product onto the brush. So you have to work quickly to wipe it on a paper towel in order to get old makeup off the brush. A pro about this one is that the brush feels like it dries the brush completely so you could use the brush again immediately after cleaning. Probably good for professional use. It seems to take nearly of the product off however when it dries on your hand it leaves a white dry residue. it also has kind of a pungent chemical smell that seems to be masked with a vanilla scent. I'm not sure if this is related but this product has broken 2 spray bottles I've used to hold it in which has never happened with my other brush cleaners.

The Sephora Cleaner worked to me very much like a baby shampoo would. I pump out a little product into the palm of my hand and swirl my brush into it then run the brush under water. I may repeat this step until the water runs clear. I then squeeze the brush dry and make sure they dry in shape. A brush guard may help with that.
Baby shampoo worked pretty much the same as the Sephora cleaner in my mind. Maybe it doesn't contain any anti-bacterial to it though.
I personally wasn't too crazy about the EnKore DIY formula. It smelled chemically and I didn't feel like my brushes looked any cleaner than baby shampoo or the sephora cleaner. Although I initially thought it was a cool idea to make my own brush cleaner and possibly save a lot of money. I found my own mixture to be the least appealing in the end.
