AHVA IPS vs AH - IPS panel type differences?

[Bape]

What are the differences between these two such as which is newer and superior?

AHVA IPS is faster and better contrast but less color while Ah-IPS is better for color?(according to some people). Plus AHVA-IPS is usually on ASUS and AH-IPS on LG.

Any other differences?
