Ya know... I think my ideal #nostr client would be the love child of nostr:npub16c0nh3dnadzqpm76uctf5hqhe2lny344zsmpm6feee9p5rdxaa9q586nvr's Primal and nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn's Coracle that's been raised by Tweetdeck. And before someone says to "just make it yourself", I have neither the knowledge nor the drive to do it.
Primal has the algorithms, a lot of content moderation tools, and their "trending" list. And it seems they are taking a page out of Bluesky's book and ultimately allowing users to outsource all of that. They also have a Twitter-like UI, so that helps a LOT.
Coracle has the layout in terms of how threads are nested, it shows what relays a given note has been posted to, and its advanced search features. It also has a neat relay review system, the NIP-32-based lists could be useful, if a little underutilized, and it's one of the few web-based clients that implement nostr connect. And I almost forgot to mention support for multiple accounts.
And finally Tweetdeck. Good god, where do I even start? Multi-collum layout allowing you to have multiple feeds on one screen and scheduled tweets were the two biggest features. Granted I never did use that second one.
Side note, I've actually managed to post at least one thing a day for two weeks straight so I'm slowly breaking out of my shell.
