The most obvious difference between them is the price, as Hoola bronzer runs for about $30 while NYC sunny is about $4 in the drugstore.

Hoola (left), NYC sunny (right)The colors are different as well. As you can see in the pan, NYC sunny is a tad bit more orange than Benefits hoola bronzer, which is a little bit more olive toned. I find that Hoola suits my skin tone better, as I have yellow undertones, and yellow and olive go hand in hand together.
NYC sunny is also a really sheer bronzer, while Hoola is a bit more pigmented. You can also see the quality of the Hoola bronzer as the powder is very fine and creamy in a way. The Sunny bronzer is a bit harder to pick up in the pan, and it took me about 3 swatches to get a good color payoff in my swatch above.
They are both great bronzers if you like the natural look.
However, If I had to choose one bronzer to buy, I think it would be NYC Sunny. I personally think that Hoola bronzer was a waste of money, and it barely even shows up on my skin (since I have pretty tan skin already). And if I wanted a matte bronzer, why should I pay $30 when I can buy a darker powder from the drugstore for cheap? NYC bronzer is a great bronzer for beginners. Its inexpensive, it looks natural, and the packaging is much more compact than Hoola Bronzer.
However, if you have fair skin, are a fan of high end products and you want a bronzer that is smooth to apply and not an orangey tone, Hoola bronzer would be the a great choice for you.
