That is entirely subjective but I would say some still prefer CRT and Analog video, which these retro consoles also provide. There are also some benefits for it like no lag and better graphics due to the natural blurring of the CRT but at the cost of space and screen size. CRTs are bulky.
You can even get better and new alternative retro consoles. As in consoles with HDMI out and upscalers that will run old games.
Which is better for 8- and 16-bit games, HDMI out with an upscaler, or analog video out with a real CRT?
