For me SimpleX does everything I need. Unified push would be nice, and would address battery usage. I don’t need or want message sync, so that’s not an issue.
They all have tradeoffs, so it’s just a matter of your priorities. For instance I’m OK with the higher battery drain because it’s not using Google.
Off the top of my head though I can’t think of any that are based on a persons name. Rod, Chain, Peck, Hogshead etc.
