Overall I personally like the CRT as it allows exact pixel registration at lower resolutions.
This is especially nice for games running in NTSC or PAL resolutions with a scan doubler.
Also the 4:3 ratio "feels" like an Amiga.
However at the exact native resolution of an LCD monitor, the LCD monitors seem superior, as they are extremely sharp. However, I cannot stand low resolution extrapolation on a high res. monitors, they always look "soft" or worse as there is antialiasing going on.
