MSK vs SQS + SNS

Question

I am deciding if I should use MSK (managed kafka from AWS) or a combination of SQS + SNS to achieve a pub sub model?

Background

Currently, we have a micro service architecture but we don't use any messaging service and only use REST apis (dont ask why - related to some 3rd party vendors who designed the architecture). Now, I want to revamp it and start using messaging for communication between micro-services.

Initially, the plan is to start publishing entity events for any other micro service to consume - these events will also be stored in data lake in S3 which will also serve as a base for starting data team.

Later, I want to move certain features from REST to async communication.

Anyway, the main question I have is - should I decide to go with MSK or should I use SQS + SNS for the same? ( I already understand the basic concepts but wanted to understand from fellow community if there are some other pros and cons)?

Thanks in advance
