I have no NV but I do not doubt how astonishing emission nebula look with it, as compared with visual observation. If they weren't so expensive, I would certainly go for them.
At the same time there is a certain magic doing eye visual only under dark skies.
Most nebula are very faint observed visually as compared to NV.
Under dark skies with a medium aperture (10") and a filter, there are about 30 large emission nebula (not counting planetary nebula) that will look nice, with many dozen others being visible but very faint.
A non complete list, from brightest to faintest, would be: Orion, lagoon, M17, M16, M78, Veil, north America, monkeyhead, running man, pacman, crescent, Rosette, Flame, pelican, skull, northern lagoon, Sadr complex, Thor's helmet, Helix, Ic410, coccoon, iris, bubble, footprint, Medusa, ngc1980, ngc2170, California, wizard, Heart, Soul, Seagull, Fox fur, cosmic bat, Merope and maia, Elephant trunk, gamma Cass, lion mace, Dryer complex, Horse head and Ic434, lobster claw, propeller, lambda orion, jelly fish, barnards loop, flaming star, cave, tulip, flying bat, witch head and lower nebula.
The nebula listed after the Elephant Trunk are quite faint and the ones listed after the propeller are very faint.
I omitted many small bright nebula and some very faint unnamed sharpness nebula.
