Abap Proxy vs Odata Proxy

Hello Dear Experts.

I just watching this post: Exposing master data as ODATA service from S/4 HANA on-premise | SAP Blogs

I have a question , currenlty we have many scenarios ABAP Proxy on ECC On Premise with SAP PO.

Is there any advantage to create OdataProxy vs ABAP Proxy when we migrate our ECC on Premise to S/4 Hana? and use CPI, or in what case can we use Odata Service?
