I think this depends very much on how you use the tools.
My experience with email is that people have subject lines, email explicitly identifies to and cc recipients; email is threaded; email often has quotes/excerpting/highlighting from prior parts of the thread.
On the other hand, most chat usage I see is dependent on temporal aspects for threading (people under-utilize platform features for replies etc), tagging is generally only done to ping people to attract attention, chat groups are frequently reused for multiple different purposes.
Leaping to a point-in-time within a chat stream is often a bad user experience, with having to scroll up and down through unrelated stuff to find what you’re looking for.
Stuff in email is just massively more discoverable for me.
