iMessage is a very limited and glitchy app when it comes down to it.
Just from the top of my head: no E2EE by default. Gifies are restricted (and censored). Reactions are clumsy (there are two rows of different kinds of emojis to choose from now). Adding photos or sharing location is complicated compared to Signal or Whatsapp.
Search is ... well, I hope you don't really need to find anything. Delayed notifications on macOS for no apparent reason, and in 2025 you can still end up with multiple entries for the same contact...
