After some tests, my understanding is that (please correct me if I'm wrong):

ChatGTP Action Card:

• Will be able to natively find your resources from SalesIQ's Articles, FAQ, and Zoho Desk.
• Will use GPT-4 (4o?) only to summarize the answers it can find in the aforementioned documents.
• Is most probably less performant in providing contextualized answers.

ChatGTP with Plug Integration:

• Uses GPT-4o integration natively to handle all conversations.
• Is much better at answering written questions.
• Is harder to use with other SalesIQ chat functions (e.g., it acts like a separate brain, so if you ask to book an appointment, it will probably suggest contacting the company and won't be able to show the Zoho booking card).

Am I right? Do you have anything to add?
