Some vehicle inspection sticker stations may require your windows to meet legal requirements as well. Many quality tint installers that have been in business for a while will only install legal tint and may place a small sticker on the window before tinting that says this tint meets code. I suggest going with the darkest legal on the sides. The back window does not have any restrictions and can go as dark as you prefer, which will make the side windows appear even darker, however, they will still be legal.
This will help you see better in the dark as well.
My 2 cents!
