I have a few PVM's and I love them.
All of the following is in regards to RGB connections with arcade games in native resolution.
They are not as authentic as a curved tube, but I never notice at all when I'm playing. It looks just slightly odd at first maybe on the true flat one I have, but the older ones don't even register as being different to me.
I'm much more distracted by the extremely pretty colors on screen. The Trinitrons I have seen have better color and contrast than any arcade monitor I have ever seen.
The stripe pitch is noticeable, but has no effect on me. I prefer its on most games. Only on a very few older games, like Galaga, do I like a blurrier dot triad style. On trinitron PC monitors the dot pitch is very very fine indeed though, and does not look good IMO. But on the older PVM's it is a non-issue.
The wire is simply invisible to me. I noticed it when I first got it, but that was years ago and when I look at one now I never ever see it. Even on completely white screens. I have to force myself to see it.
I have a lot of different monitors of makes and models, and I firmly believe my little 12" trinitron has the objectively best looking image among them. The larger 19" ones are a close second. It's not necessarily the most accurate image, but based on pure visual appeal I think it is the winner.
