I find the first product picture confusing.
At first I have no idea what it is you are offering for sale.
So, I'd obviously go for one of the other two. But frankly, if you go for a white background, why not go all the way and make it pure white?
I know the answer, because that is what I used to do. It looks great, but it takes a ridiculous amount of time.
Still, I'd go with a background without clutter.
