Although it seems clear to me that Pout Paints are at least partially inspired by Lip Tars, Sleek is advertising them as "a truly unique lip product... [that is] like no other." That's simply not true. This product is not unique and it is like OCC lip tars.

Right off the bat, one important difference is worth pointing out: Sephora currently has 48 shades of lip tar available. The Sleek website has seven shades of Pout Paint. That's almost a sevenfold difference in terms of straight up color selection. And since Sleek is missing important colors like black, white, and yellow, there's no way you could make up that color variety through mixing.
I did my traditional "four hours and meal" test to check out the lasting ability of lip tars vs. pout paints.

Note: Natural lighting is giving weird color variability. This is the same as the OCC Lip Tar in the "before picture", I pinky promise.
I have also found that pout paints are much more prone to separation than my lip tars. I have never had my lip tars separate (I know other people have but I have not!). This pout paint needs to be sort of awkwardly smooshed around in the tube every time or it become a little pigment suspended in greasy liquid.
These two products clearly do not perform equally. However, the price difference may justify using the dupe for some people. Sleek Pout Paints retail for $6.49 for 0.27 oz ($24.04 per ounce), whereas OCC Lip Tars come in at a much steeper $18 for 0.33oz ($54.54 per ounce). That makes them over twice as expensive.
The dupe-worthiness of these products really comes down to the reason that you are drawn to OCC lip tars. If you like lip tars for their wide color range and their fantastic staying power (which is why I like them), that really won't cut it. Save your money. However, if you specifically love the color "Stalker" and find this sort of consistency appealing, this dupe might do the trick.
