Zoya Avery vs. OPI Don't Pretzel My Buttons

Since receiving OPI's Don't Pretzel My Buttons, I have been curious as to how it compares to Zoya's Avery. Surprisingly, I can barely tell a difference between the two polishes. I had to really dig and stare at them for a while to even come up with a few minuscule ones!

OPI Don't Pretzel My Buttons (index and middle fingers) - 3 coats for opacity, a slightly thicker formula, dries faster than Avery, may be a tiny bit more pink in color, but it is very hard to tell.

Zoya Avery (ring finger and pinkie) - 2 coats, a little more brown in color, with a tad more natural shine on its own.

I tried all different types of lighting and stared at these two polishes for a good 5 minutes and I just can't come up with any other differences. They are definitely dupes! I do like Avery a little more, though, just because it took less for opacity and had a better brush. Besides, it is Zoya and I looooove Zoya! ^.^
