I just started reading this. Very interesting stuff. Here’s the comparision of the Samyutta Nikaya and Agama:
The overallstructure of the Saṁyutta Nikāya/Āgama corresponds roughly with the four noble truths. Bhikkhu Bodhi notes that this correspondence is more apparent in the Chinese than the Pali. The five aggregates and six sense media pertain to the first noble truth; dependent origination (Nidāna-saṁyutta) to the second and third; and the path is the fourth. We may refer to these fundamental topics in a general sense as the ‘saṁyuttamātikā’. We mentioned above that the backbone of this Magga Vagga is the 37 wings to awakening; in the Chinese these are preserved in an order that more closely follows the standard Sutta sequence. We therefore have a number of indications that the Chinese is more structurally reliable than the Pali: the position of the Bhikkhu-saṁyutta; the overall correspondence with the four noble truths; and the sequence of the wings to awakening.
That’s from pages 48 and 49. https://santifm.org/santipada/wp-content/uploads/2012/08/A_History_of_Mindfulness_Bhikkhu_Sujato.pdf
