Is kelp better than seaweed?

Excuse me, I'm quite curious about a subject matter that's often debated in culinary circles. Could you please help me understand if kelp is indeed superior to seaweed? I've heard various opinions on this topic, but I'm looking for a more informed perspective. What are the key differences between these two aquatic plants? Are there nutritional benefits that kelp offers over seaweed? Or perhaps, are there specific culinary uses where kelp shines brighter than seaweed? I'd appreciate it if you could elaborate on this matter.
