very close but no cigar...
OK, it's comparing single sheets, with single sets of measurements, but the TFP slightly edges the IFA49 in its gamut (the IFA49 is an older box of paper though)
The surface finish is slightly different, however I suspect that if you were to use the TPP/EFP profile with the IFA49, then a lot of people wouldn't notice the difference ;-)
If anyone wants the comparisons of the measurements or data, to satisfy their curiosity even further, then feel free to mail me...
