Every diamond I've ever loved has been a misfit, and yours is a triple Ex stone! That already means that it's cut better than, like, 98% of the round brilliants in the world. It's gorgeous, and you looked beyond the paper and chose the stone based on what your eyes and heart told you, which means it's undoubtedly better and more beautiful than the smaller tabled stone, TO YOU. And that's what matters most!
There's a strong bias on PS for diamonds that have parameters for a specific look, but truly can the human eye distinguish between subtle differences in light return? And can we say without a doubt that light return is the only measure of beauty? What about fancy cuts? Are they less beautiful than ideal cut RB's because they return less light? What about old cuts - are they less beautiful?
Beauty is completely subjective - enjoy your gorgeous ring!
