H-beta or 0-lll filter

From a light polluted environment, I'm hoping to improve views of nebula and
galaxies with an effective filter. There is some sky darkening with Orion's
SkyGlow lowband filter, but it also dims the target a bit. Will a
hydrogen-beta or oxygen filter improve contrast and resolution enough to
justify spending the bucks? Which is the better filter?
