If you're asking the difference between "logic" and "aesthetic", here's my response:
I'd like to answer your question, with a question: Do you know what they are? You either don't know what logic is, don't know what aesthetic means or don't know what either means. If that's the case: You should know what logic is. I'm not going to explain it. Aesthetics, for lack of a better description, is basically what something looks like. Logic is how you do something(kind of), and aesthetics is what something looks like. They aren't really related. There is a huge difference between them.
Sorry if I came across as a little rude, but it was the best way I could think to answer your question
