I echo that Lifecolor is a very fine paint, but when deciding on which paint to use there is another consideration to take into account. Colour matching and preference.
This picture (of the bottom of my Pzr IV E) shows three different shades of what should be the same colour. From left to right Tamiya, Vallejo, and Lifecolor. All these are labeled as Dark Yellow or Dunkelgelb. Lifecolor additionaly adds that it conforms to RAL 7028

Observe the difference between these, with the Lifecolor one leaning towards a flesh colour, and the Vallejo leaning sofar to brown it has really put me off using it for ETO German Armour.
I have not yet used the Vallejo on a model, so I'll reserve my opinion on it, but I do know that I have gone back to Tamiya for many base colours, such as Dunkelgelb and Olive Drab. Apart from Vallejo's reluctance to stick to my models without a clear coating, I prefer the shade of Tamiya's colours. I do like the 'rough' surface of Tamiya, as it helps the pigments to adhere. You can also buff the surface, which gives a perfect 'polished' effect.
Vallejo is however a superb paint to handbrush, and they do a good rage of German Camouflage uniform colours.
Horses for courses..
