Best freeze-dried brand?

[swifty]

I'm aware of the generally accepted best pellet/frozen food brands, but I've never found anything on freeze-dried. I'm also aware pellet/frozen is much more nutritional, as I've been feeding my fish that for the last 8 months. My new jack however, is still learning his surroundings and I'd like to get him to recognize me a bit more. He already knows I control the food, as he comes up to the surface, but I'd like to let my other housemates feed him, and I feel the best way would be the freeze-dried krill bits. I'd also like to do it as well, so he'll be a bit more comfortable when I stick my hands in the tank to do water changes.

So, with as many brands out there, is there a clear front-runner for freeze-dried in terms of safety/quality like there is for pellet/frozen like NLS/hikari are?
