I always thought Prodibio was the more expensive option for larger tanks. I know for my tank I worked it out to around 2 full kits a month which is around $120 or so. I think I spend about half that on zeo for a similar line up of additives plus the reactor media.
In terms of which is better, peoples opinions will differ but in general comparing reviews will suggest zeovit is more demanding, contains higher risk but offers the best results. Prodibio is less demand, less risk but lower results. Which is right for you depends on the goal, if it doesn't relate to SPS coloration I wouldn't use either and stick with bio-pellets & gfo if anything at all.
