Meta for Business vs Mailchimp: Which is best for you?

I appreciate that it helps with social media management, gives me the blue checkmark on my social media profile, and allows cross posting between Instagram and Facebook

The benefit of being able to advertise on their platforms outweighs the frustrations: constantly removing targeting options that are helpful for us, always making it harder to build custom campaigns versus their AI suggested, and the nonexistent support is frustrating when we have ads that get disapproved.

Mailchimp allows us to quickly create, automate, and analyze email campaigns, making it an excellent choice for both beginners and seasoned marketers.

For agencies, they forced that the pre-paid credits expire in a year, and the list plans aren't worth the money unless you send a lot of frequent mails. If you send campaings from time to time to different customers, unless your volume is huge, fees make it unpayable. If you are an end user, then the story is different and prices will make more sense (maybe that's their idea of customers right now).
