Balling, dosing, CaRx, etc are all just different ways to do the same thing. They all have pros and cons, and they all have people who love them and hate them. Often when someone bashes a method, it is generally because they had a bad experience with it which doesn't mean the method is inherently flawed. For every big baller that doesn't run a CaRx on R2R, I can find you one that does on a different forum. There are a million ways to successfully skin a reef.
I have run all different ways and tend to like reactors because I find them easier to set and forget, tune, and cheaper over the long term. This is especially true for larger systems. On my 300 at home I sadly moved from Bionic dosing because it just got too expensive. IMO, the most important pieces of kit in a CaRx set up is an adjustable peristaltic pump for feeding the reactor as needle valves or other ways of controlling the input to the reactor tend to clog with particulate and need adjusting often.
