Dean Martin is better then Frank Sinatra because he is a better actor then Frank Sinatra, and his singing style is less robotic and more footloose, plus he is in his own television show, he is also a very funny person who knows what he is doing.
Frank had the charisma, no doubt,Sinatra all the way. Dean Martin was actually always drunk on set and in studio. Dean has a good voice, but he sounds just like Bing Crosby. Frank has a voice of his own.Frank was great entertainer, and Dean knew that and respected that too! Two of them where like brothers, and respected each others personalities and talents. Frank is after all the Voice, and sometimes people forget that he was a great entertainer as well! Nothing like Dean, but great non the less!Frank Sinatra without a doubt. He has some classics as does Dean Martin, but just hearing My Way still leaves me feeling emotionally charged. That song just sums up the greatness of Sinatra really.I think they are both absoluetely amazing, and i wish people could still appriciate their music. I have been listening to both for many years, and they will both always have a place in my heart.
I agree that Frank Sinatra is a great singer and he was actually the singer I heard first, but I would politely like to say that in addition to English Dean Martin sang songs in Italian which gives his music a more personal feel because he is of Italian heritage.
