Benjamin Discovery Altaros versus Huma

I'm new to the forum, but I did search for a comparison of the Altaros versus Huma regulators and found nothing comparing them.

Can someone compare them and list the relative merits of each?

I have a Benjamin Disco that has been fitted with a BNM breech and shroud. I built a power adjuster but without the regulator It's prolly not the best for accuracy. Still trying :>)

Thanks for your help
