I've been on Amethyst the past couple of days because Iris seems to be having some issues keeping up. I still like both quite a bit, though.

Yes the same i'm using both and Amethyst is clearly much faster
Amethyst seems to be picking up data from all the relays faster but the UI is so jarring to my eyes I can't stand to use it. I don't know why, just something about the way the notes and replies take up space on my phone screen doesn't work for my brain. I spend almost all of my Nostr time on my PC using Iris in the browser.
