You got LCDs these days that go up to 500hz, CRTs aren't the best at it anymore really. Maybe they still have slightly better response times, but even that is a losing battle for them.
iirc it's still 0.001 ms on CRTs vs 0.1ms on the best LCDs?
But that's not their main advantage, their main advantage is having absolutely zero motion blur thanks to natural, inbuilt BFI (having one frame that just gives way to another causes some amount of them blurring together in your visual cortex, while if there's a black frame in between that keeps them perfectly separate, and even when running, 90% of a CRT's screen will be black at any given time). Also that natural BFI makes them look a lot smoother than an LCD, like a CRT at 60hz will look as good as an LCD at 120hz.
The CRT is not the problem, I have two myself, one high-end graphics monitor from 2003 and an average office monitor from 1993.
The issue is having the CRT right beside an ultrawide with no other monitors (like, say, a 16:9 or 16:10 for things that do not play nice with 4:3 or ultrawides), and also the part where that ultrawide is the the crime against good taste that is 32:9
