My money would be on Lumicon, by a long stretch.

The best way for you to decide is to get hold of the transmission curves for the filters and to compare things like how wide the band pass width is , how well they reject the undesireable wavelengths and how well and consistantly they transmit the in the bands they specify.

Other aspects to consider are how they are manufactured, price, and to read the threads here on filter selection and on other boards, and to take everything the sales people tell you with a grain of salt.

It also depends on how you plan to use them, visually ? as a front filter on a lens (if you can do that even ?) as a dropin in a camera body ? in the optical path of a telescope camera system ?
