Personally I think that omega one is superior to both new life spectrum and hikari based on the ingerdient list. None of my fish ever really liked new life spectrum.
For example, the first four ingredients in newlife spectrum is "Whole Antarctic Krill Meal, Whole Herring Meal, Wheat Flour, Whole Squid Meal"
notice that each fish is a "meal" and that wheat flour is the 3rd ingredient
The first four ingredients in my omega one shrimp pellets are as follows:
"whole shrimp, whole salmon, cod, whole herring"
notice that the omega one isn't a "fish meal" it is whole fish as opposed to NLS which is "fishmeal"
The omega one super color flakes first four ingredients are as follows:
"whole salmon, halibut, seafood mix(including krill, rockfish, and shirmp), wheat gluten"
also notice that wheat is the fourth ingredient here not the 3rd which indicates less filler is used as opposed to the NLS where wheat was the 3rd ingredient.
