I use to sell both of these brands, they are made by the same guy, just differently named companies. To the best of my knowledge they are essentially the same thing, only difference is that one is slot ported, and the other has the standard cylinder type porting. I've used them both a bunch and they are identical in performance. I've used this constriction exclusively with 7.5 shot on any rabbit targets out to 40 yards or so. There were very few that got away! Good luck!
The habit of changing chokes is greatly over rated and is more of a marketing ploy than actual "shooting fix". No matter what choke you use, the core pattern will be the same. Learn to shoot with 1 choke constriction, put the muzzles where they need to be and the rest is easy.
