To me, they’re not the same feature, so I wouldn’t compare them directly.
What I find interesting about the NIP-05 feed is that it aligns really well with the way we browse feeds. When I come across an interesting user, I can click to view their NIP-05 feed and naturally discover other people who are similar, it’s a more serendipitous kind of discovery.
Follow packs, on the other hand, are more suited for when I actively want to find a bunch of new, interesting people. I open the follow packs page with a clear intention and purpose.
