A client that is basically a ripoff of Telegram would be ideal for me, for what it's worth
Main features I like are replies, reactions to messages (also double tap to react with a default emoji), and that view where you can open a chain of replies like it's its own conversation (I'm assuming this is what is meant by "threading"/"threads")
Lastly, maybe the uncompressed and compressed photo/video options if that's not already a thing
If it had the above I would probably like Discord style too
Half the voting population, more specifically
Or I guess in this case, half of those polled
