Katz Eye screen or Canon ef-s?

[vd853]

Hi, I played around with old SLR cameras in the past, and I like how these screen work for manual focusing.

Would you guys suggest the Katz or Canon screen? I have not tried either, but the Katz w/ brightness enhancement cost over 3x as much as Canon's! is it even worth it?
