ee I don't think providing comparison is something for the F5 Devcentral community channel. F5 is great network based system and layer 7 proxy (especially for web traffic with the ASM/AWAF module) but you need to be aware what you want and what you are trying to achieve as you mentioned " which might be not from the response" if the sensitive information is autogenerated by a javascript on the customer devices (or in a mobile app) and not from a web response then endpoint DLP may do the job and you better review it with a DLP vendor of your choice.
Edit:
I forgot to add that for binary files that could be in the response you will need an external DLP to scan them as F5 AWAF/ASM is Web based solution and you then can use ICAP for this.
