Which is the best shadow to download?

I have no idea on which shadow to download because there are so many to choose from. And also, does it make your game better? or does it ruin it?

it makes it better but i cant decide a good one to choose cause they all good

Just d/l them all and try them for yourself. All you're doing is copying and pasting a file, takes 2 seconds.

Try them and then use whichever one looks the best to you.
