We use CloudWatch for less often queried data but it has minimal indexing so it's not very good at lots of ad-hoc queries for discovery. More feature-rich platforms also allow things like ad-hoc metric generation and a more robust ingest pipeline In addition, CloudWatch metrics aren't great (for custom metrics) so you end up using CloudWatch + <something else> so ideally you just use only <something else>
