Stress Coat+ Or Prime or Jungle Just Right? Expert Fish Keepers Only Please!?

So right now i'm using Stress Coat+ in all of my fish tanks. Then i read that the aloe messes with their scales so that they'll produce more slime. Is this true? And that it covers up ammonia so it won't show. Idc about if they take it away or cover it up thats why i do water changes. But When it comes to conditioning the water and helping heal fish which is better? Also does anyone have experience with Fish Protector? Is it good?
