Sorta.... if I remember the DF video right they really don't delve into the downsides enough....
Some of the cons off the top of my head.
- Heavy AF
- Colour drift, requiring re-calibration over time
- Image geometry drift requiring re-calibration over time
- Image geometry calibration needs to be done per resolution and Hz setting
- Image geometry, colour and brightness are not perfect till the CRT warms up
- Not very bright
Not to mention all the problems that come with tech as old as the widescreen CRTs are
