I don't know about your school, but gen chem and organic are very different subjects. Gen chem is heavily math based while organic is based on concepts, spatial orientation, and mechanisms. You can memorize formulas for gen chem and do just fine, but you cannot just memorize for organic- you have to actually understand the material.
What I'm saying is, I don't think performance in gen chem is necessarily an accurate indicator of performance in organic chem.
At my school, honors organic is perceived as being easier than regular. My best friend withdrew from regular organic and had the highest grade in the class in honors. To me, if you want a smaller class size and more personal attention from the teacher, take honors.
