Difference between Applying May 30th and June 9th?

Everything in my app is ready except my PS, my AMCAS is all filled. I just have to polish my PS and maybe polish one or two activity descriptions, but I don’t want to rush my app if I can get an even better PS in my app. Is there really a difference between submitting my app on May 30th vs June 8th or 9th? Will it still be in the “first batch”?
