Please elaborate. I'm not questioning what you say is true, but I'm interested in a tool like this one and would love to know more before choosing one or another.

Do not have that much experience with Huginn but you are probably right. As n8n is new and Huginn is already around for many years it would be surprising if they would be equal in every way. Anyway, I am quite sure that most that can be done with Huginn can with a limited amount of work also be done in n8n as creating new nodes is very simple. (I am the creator of n8n)
