you know it doesn't really matters who's better. if a tagahanga chooses GRUVIA or GRAYLU let them be. but if it's my opinion then i madami like graylu even though its impossible :)
P.S.
i also think that hiro made lyon like juvia so that gray will realize his feelings but he might change his mind and continue this pag-ibig tatsulok i mean when i was surfing in the internet i saw something very incredible!!!!!that LYVIA and GRUVIA couple are at SEMI-CANON!!!if it was at semi-canon does that mean that the lyvia fans just catch up at the fans of gruvia (not so sure) ?! then it also means that if hiro continue this pag-ibig tatsulok then fairy tail might have madami and madami fans!!!!don't you agree??!!!BUT THIS IS ONLY MY OPINION THIS IS ONLY WHAT I SAW AT THE INTERNET!!!!if you want maybe you will go to this web site so that you will know what i mean
