Here's a decent write-up about the scenes in the trailers, and not in the final edit, and the differences between the revised Whedon cut and old the Snyder cut. The article also highlights what scene was retained from the original Snyder cut and what was added by Whedon in the reshoots. Some you can already tell, some I was quite surprised about.
