How is working in threat intelligence within an MDR?

Noticing a lot of MDR companies popping up with their own threat intel teams (e.g., Red Canary, Arctic Wolf, Rapid7, Reliaquest, SecureWorks, etc.)

I have heard working within SOC’s of these types of companies can lead to getting pretty overworked due to the amount of different customers and environments you are monitoring. Does this still apply to the supporting threat intelligence roles as well?
