Should I use Azure Data Factory or Synapse?

Hey there, I'm trying to decide between Azure Data Factory and Synapse for my data processing needs. Could you help me understand the key differences between the two? Specifically, I'm interested in their scalability, ease of use, and integration capabilities. Additionally, how do they compare in terms of cost-effectiveness for handling large datasets? Any insights or personal experiences you can share would be greatly appreciated. Thanks in advance!
