Default How to test which filter is better?

Need some advice on testing the 2 UV filters I got.
One is Tiffen and the other is Kenko 58mm, neither is multi-coated.
I want to give one to one of my friends who also has T2i but I can't decide which one to keep.
Is there a simple test to figure out which one has the least effect on image quality?
Thanks for ideas.

Put one on the end of your lens, take a photo, take it off and put the other on, take another photo in the same light/exposure conditions. Open each image in you photo editing software, enlarge to 100%, decide.

I already did that but both look same.
That's why I wanted to check other ideas.
Someone mentioned to see if white paper looks white on both... they do...

I did check that out but it only has Tiffen test results.
The kenko one that they have is Mulit Coated with good review and mine is just regular kenko.
But since the basic Tiffen had the worst result there, may be I should get rid of it.
