I have no idea what does that part number cover.

I prefer multi-gapped ferrite toroids, and gapped ferrite pot (or RM) cores with litz wire.

I copy what I answered to you in PM:
"There are a huge number of usable solutions, but I have no idea which is achievable for you, and which is the "best" for you. There are many optimisation target, like price, size, weight, idle loss, full load loss, EMI, etc... There is no such thing as "Best", because it depends on your preferences! This is why you find different cores in different products."

For example if you choose very low permeability, then idle loss can be very low, but full load loss will be higher. You have to decide which is more important for you!

There are general rules, but they never say what is the best, they say "if you do this, you will get that". If you want to know, you have to ask about basics, not the solution!
