How about neither package gets it right for all meters, kind of hard to do a meter shoot out with software packages that don’t support the hardware properly.
ColorFacts uses the Spyder2 only in LCD mode with the diffuser on which on a true CRT will be off. HCFR uses the Display2 in LCD mode for Plasmas because of the scan rate sync issue which again will be off.
Here is how each meter should be supported and is in CalMAN v3.
x-rite DTP94 has support for LCD and CRT modes and does not need a scan rate sync for CRT. So you use CRT for all phosphor based devices and LCD for all the rest.
x-rite Display2 has support for LCD, CRT and diffuser modes but does need a scan rate sync to work in CRT mode unless you know how to disable it. So you use CRT for all phosphor based devices including Plasma with the sync disabled and LCD or diffuser for all the rest. The Display2 can also have issues with fast DLP colorwheels or the new fast scan LCDs unless you know how to set it up.
x-rite i1Pro has support for all display types with two modes with and without a diffuser. But it lacks good low light capabilities unless you have a system for dealing with it and I'm not just taking about averaging multiple readings it needs to be much more than just a simple average. You use it without the diffuser for most display types and with the diffuser for a direct source reading like from a front projector.
x-rite Chroma5 is the big brother to the Display2. Has support for LCD, CRT and user. So you use CRT for all phosphor based and LCD or user for all the rest.
x-rite Hubble or also known as the Sencore OTC1000 has support for Projectors and all others. It is really sensitive to aiming I guess that's why they built in a laser pointer. It also has to deal with ambient light since it is not a contact meter.
ColorVision Spyder2 has support for LCD with the diffuser on and CRT with it off. It does need a scan rate sync to work with CRT's. So you use CRT for all phosphor based devices except Plasma and LCD for all the rest. The Spyder2 can have low light issues unless you extend it's reading time to over 8 seconds.
DataColor Spyder3 only has a single mode for all display types since the diffuser is not removable.
