One reason that some amateur prefer unfiltered photometry is many CVs  
is too faint to multicolor photometry for amateur.
And some professionals prefer high-speed spectroscopy rather than  
multicolor photometry.

I prefer V-band photometry rather than unfiltered photometry because  
it is more tolerant for extinction change during photometry.
