The issue with the tristimulus meters is that for a broad spectrum light source, they're good. However for narrow light sources (Like Laser, OLED...) it only takes a small error in the filter to make a large error in the measurement. The wider the colour gamut, the narrower the light sources need to be.
If you look at the SpecraCal page,
http://calman.spectracal.com/meters.html , you can see that the cheaper meters aren't designed for use with OLEDs for instance. Personally, I have a SpectraCal C3 (and access to a Photometer) - but I'm not sure it works with many software tools.
ColorChecker passport - I use it when shooting RAW video. I create a camera profile for a known lighting condition, apply that to all the raw files, I then have a technically accurate image (providing the image is exposed within 1 or 2 stops of where it needs to be). You can then add a creative look to it really easily.
