O III filters

Hi, Can someone with user experience contrast and compare the different O III filters being offered by Lumicon, Orion, Baader, and others? Is the precision of the $200+ filters worth the price difference being asked? I assume the more precise the cutoff the higher the price, what other factors are involved? Thanks for your input.

i can only comment on the two i have, a Celestron O3 and a Televue O3
Significant difference, as the veil and north american nebula are obvious in the TV, but barely show in the Celestron

Get the Lumicon, best I've found.

The Televue is not tight enough in filtering for high contrast.
