What I like about 1-3 is that they are innovating in a way that has impact.  For example, ditto is providing a new scaling architecture and bridges to millions of users and apps.  Damus is an invaluable client and public relay, always pushing new innovations, npubs, zaps, notedeck -- it has already helped level up nostr once -- and may do again.  Iris/Snort, Martti has been working on this for over a decade, has experience, has built social graphs even before nostr, knows what he's doing.  All 3 have great devs that stay humble, and are able to put their egos to one side and put the needs of the project ahead of their own needs.

IMHO the other end of the spectrum are clients that are in their comfort zone and want the protocol to conform to them.  Little things like the 1984 reactions.  Amethyst also is known for high bandwidth.  I would like to see more diversity on android.  I dont want to say too much negative, rather stick to the positives.
