Hi mike, all the WN artists grade are artist level paints and are professional grade. I think the series 2 number you are referring to is the price grouping for whatever pigment/processing is used for that particular paint. Both the pigments used and the manner in which they are made contribute to the pricing variations within the entire artists range of paints. It doesn't mean that they are a higher quality level, it just means that they are more expensive to make so they charge more commensurate with their cost of manufacture. At least I think that is what you are talking about.
Wintons use less expensive pigments and have two levels of cost for their entire line, WN artist grade have four or five, I forget exactly. I think you might be asking is it worth it to buy the series 2 wintons vs the artist grade paints and that is debatable but I would answer yes, I prefer the artist grade over the winton student grade, in the Winsor Newton lines anyway.
You don't have to be crazy to paint, but it helps!
