Definitely Olly Murs, i feel he has a better quality to his voice, he is better live, i personally think. I also think his style is better and his music, although i'm a huge Фан of his and would consider myself biased!!!!
Olly Murs <3 100% gorgeous, perfect personality, looks aren't bad, best voice, kind, does loads of charity events! Plus, I Любовь him so much! I am quite biased but honest.
