There's not generally much difference if you ignore green/amber screens,
and assuming you're talking monochrome. Some monitor tubes have longer
persistence phosphors though, to reduce flicker. A few have overdone it
making scrolled text a nightmare to read. As you state, the real difference
is in the signal processing, this needs a greater bandwidth to prevent
your text from 'smudging'.
