For what? For the VCO lock-in? Depends.
M6 & M7 both work in strong inversion mode, so large vdsat is normal. M6 correctly works in saturation region, M7 in triode region however, which lowers the loop gain and inserts an additional(?) non-linearity into the control loop. But this still could work well.
