I think there is a spectrum of fish food application. On one end is a aquaculture farm where fish rely 100% on artificial meals. On the other end are fish who fend for themselves. Many PB ponds are in between.

Many of us here work to maintain a diverse and healthy food chain in the pond. We feed to:

1) Enjoy watching the fish eat.
2) Keep the RWs up.
3) Ease the overall load on the food chain.

Personally I'm very happy with the results I get from the Tractor Supply stuff. Bass and Bluegill both love it and look great. After switching from three years of MVP I don't see any difference in the pond, but I do in my wallet.

Someone who has different goals probably would see a difference. Particularly if their fish are relying on the feed for a significant portion of their diet.
