How can i know which filter is better?

Hi

I'm working on a project about EEG noise cancellation.

I have used 2 filters for EOG noise cancellation.

now I want to know which one of them is better?

we don't have any information about the EOG Noise.

we have just input( noisy EEG) and 2 outputs (cleaned EEG).

would you please help me.

Thanks
