I tried many various clients, often from their early stages. It comes down to the experience and features. Specific UX decisions, like how the thread UI looks like, where are the buttons, whether it shows "replies" by default, etc matter a lot.

On the phone Amethyst works the best and sometimes I use Plebstr to try new features they add. On desktop it evolves quickly. I liked Iris, but then some features/UI changes made it worse. Astral became unusable. I don't think Coracle is there yet. I don't like the Snort UX, but it has some features that are missing elsewhere. Primal got much better recently, especially with tap-to-zap it became my to-go client, but it's still missing some features and has things broken (doesn't have DMs, doesn't have emoticons support in post creation).

Overall signal-to-noise is an issue on Nostr. It's often a lot of scrolling before you find something interesting - and I haven't found a way to mitigate it. In comparison SN is well distilled signal in the first page.
