  Mixed cold-hot dark matter cosmological models (CHDM) with $\Omega_{tot}=1$,
approximately flat initial spectrum of adiabatic perturbations and 1, 2 or 3
types of massive neutrinos are compared and tested using recent observational
data. The models with 2 or 3 neutrino types of equal mass permit as the best
fit larger values of both the Hubble constant ($H_0\le 60$ for 2 types, $H_0\le
65$ for 3 types) and the total $\Omega_{\nu}$ (up to 0.3 for 3 types) than the
model with 1 massive type. Also, they have less problems with abundances of
early compact objects including $Ly-\alpha$ clouds.
