I use a doser, can't complain, pretty simple and need some adjustment every once in a while, I use C-Balance and mag to keep the levels steady... my tank is only 100g water volume, so I do not have to dose much at the moment.
I think mostly depends on what is the demand of your tank, and maybe for a tank over 120-150g a calcium reactor is a better option due to the cost in the long run...
