Diamond quality and price difference would play a factor if it was my purchase, besides that you have two very different looks! In my opinion the rose cut ring feels more antique and sweet while the round brilliant ring feels more exotic and sexy. What is your normal style like?
Go for it! Rose gold is beautiful and that's what I would've gone for if yellow gold didn't suit my skin tone better.Not to hijack this thread, but I want this ring in rose gold with rose cuts. It is gorgeous.
