In my opinion, if you give a bluegill virtually unlimited forage, that most will ignore pellets. I have over 500 BG in my big pond, and they have tons of invertebrates, and I'll bet fewer than 50 of them regularly eat pellets. And this from fish that have seen pellets their whole lives.
In contrast, HSB with unlimited forage will have a preference for artificial feed maybe 5:1. I'll rarely find any HSB that hasn't been chowing on the Aquamax.
Cecil and Bill and others could comment with more experience, but it seems like my yellow perch prefer natural (live) prey items over pellets when both are highly available.
