Serie A
Round and well balanced. Has a bewitching mix of animal and botanical fragrances - a summery musk - opening on full, progressive flavours. The evolution of aromas takes place within a woody spectrum, followed by a honeyed trace, before ending on a sustained note of warm exotic nuances. Undeniably seductive.
Regios
A superb robusto, with delicate chocolate and gingerbread fragrance. Long lasting, it very subtly imposes its sweet and balmy aromas on the palate. Its steady burning accentuates its plentitute, making it a pleasant cigar whether accompanying a meal or a nightcap.

Hope that helps mate.. I have tried both and concur with his assessment wholeheartedly but wouldn't be able to express it as eloquently.The animal and musky part in the serie A is not present in the regios and to me signifies the biggest difference. The regios has the gingerbread aroma that a serie A doesn't have to the same degree (it is overpowered at larged by the musk. ).
