A couple of years ago I bought 4-5 different kinds of red-blue glasses (in cost range of $2 to $15) and did not find any significant difference between them in term of image quality. They all provided some level of 3D perception, but it was not great.
Then came inexpensive consumer virtual reality and it made all previous 3D technologies (anaglyph, shutter glasses, cave, etc.) immediately obsolete. Virtual reality is just so much better, not just because of superior stereo image separation and color reproduction, but also because you have motion parallax (at least as important depth cue as image disparity), you can look behind and into things just by moving around, you get 6-DOF controllers that you can use to grab the scene or objects and move them around, etc.
Nowadays it could be kind of embarrassing to show up with red/blue glasses as a “3D visualization solution”.
