Stephaan, have a look here. In the first section, Oils vs. Acrylics, Mario Fuentes dicusses just what your after. In the latter portion of part 1, you'll see where Mario compares the properties of the two DIFFERENT types of acrylic paints.
Stefaan, be careful with these "so called" reference charts as they RARELY represent what the dried color will look like. Sometimes the best way to see this is to hold the bottle in your hand although this could be a problem if you don't have any access to them. If you can't find them in a store near you, drop me a line and I'll see what I can do for you. I have nearly all the Vallejo and all the Andrea. One more word of caution. I fond that, after some experience, I don't need full ranges of a particular line. Just several will do rather nicely
