Consider that a Vega Yellow has natural gum rubber oils in it. Maxxis does not -- it is completely synthetic (ie petro plastic.)
Of course they don't work the same on the same track surfaces. You don't prep them the same either.
Vega Yellows make an excellent qualifying tire because they are generally very fast for the first 4-5 laps, then slow down.
Vega Blues won't even work until you get them warm, then they LIKE abused and heated for long runs.
To make Maxxis Pinks work in the midwest requires a lot of internal and aggressive outside wipes. Even then, they are best suited for tracks that bite up some and take a 50+d tire.
I don't personally have enough experience to say much on the Maxxis Whites other than I think they are a much better fit for our low bite tracks in the midwest without killing them with prep (like Pinks.)
Here's the way I am thinking:
No bite = Yellows
Low bite = Whites
Medium bite = Pinks
High bite = Blues
Of course this is just a generalization -- there will be instances where a particular tire will be fast than another based on sidewall, track surface abrasiveness, and of course how the tires are worked.
