100% the Code Node.
Make is great until you need to do anything truly custom. With the Code Node in N8N, you can literally execute your own logic. That means advanced switching, if/else conditions, looping through items, generating dynamic SQL queries based on variables — the kind of stuff that’s complicated or impossible (or super messy) in other no-code tools.
The AI Agent node out of the box is awesome too. That one's moving up my list fast.
What's your fav node and why?
