  We compare infrared Tully-Fisher (TF) distances and peculiar velocities
derived for spiral galaxies from the two largest datasets: the 2MASS selected
Flat Galaxy Catalog, 2MFGC [19, 20] and the Arecibo General Catalog with I-band
photometry, SFI++ [30,7]. These samples contain peculiar velocities for ~3000
and ~4000 objects, respectively. Based on a sub-sample of ~1000 common deeply
inclined galaxies, we reach the following conclusions. Irrespective to high
(SFI++) or low (2MFGC) quality of the used photometric data, about 10% of the
galaxies in both samples deviate considerably from the main body of the TF
relation. After their deletion, the standard TF scatters drops to 0.47^m
(2MFGC) and 0.40^m (SFI++). The TF distances, derived from two the samples,
demonstrate a high degree of mutual agreement with a correlation coefficient
\ro=+0.95 and \sigma(H_0r)=837 km/s. Peculiar velocities of the galaxies are
also correlated with \ro=0.56-0.59 and \sigma(V_pec)=610 km/s. We find that the
bulk motion of the 2MFGC and SFI++ galaxies on a typical scale of H_0r~5700
km/s can be represented by a dipole solution with the amplitude V=297+/-23 km/s
directed towards l=292+/-4 degr., b=-12+/-3 degr., being only slightly
sensitive to different modifications of the TF relaton.
