> With Signal you see them appear one-by-one, which is painful in a large + busy group chat.

How much delay are we talking about? In my experience we're talking maybe seconds, definitely less than 5s (depends on your connection of course). And since you only use one client at a time in theory (?), this shouldn't matter.

Or are you talking about the initial sync when you start your Signal client after a long period offline? This has improved recently for Signal-Desktop.
