I use the old style follow list as a queue of accounts that I have not yet sorted into one or more lists.

Gossip is the best client for this as I can quickly see which lists Ive assigned a pubkey.

Amethyst is what I often use for filtered views by the lists Ive defined. Coracle offers support for building your own feeds comprised of lists, tags, hashtag filters and more, and being able to save those feed definitions to come back to in the future.

This lets you use and refine your own vs only sticking to algorithms defined by others
