If you are concerned about missing notifications from a SNS subscription, you can associate a dead-letter queue.

To be honest there's no pros and cons it just depends why your designs would require multiple notification streams to be processed by the same consumer for the queue.

In the SLA you can see their uptime expectations, but like all technology you must be always be aware that there is a risk of failure.

I'd say for a solution that needs to aggregate a number of the same types of message i.e. across application or regions into a single consumer deployment then this would work out easier and cheaper to deploy.
