As far as personal prayers (prayers outside of the Breviary and the Mass), the Rosary is probably the most efficacious. The rosary itself, composed of Our Father's, Hail Mary's, Glory be's, etc. is NOT just mindless repetition. If you are just recited the prayers in a mindless fashion, you are not praying the rosary, and, for that matter, are not praying at all. The rosary is a set of twenty meditations, five for each "rosary". These meditations are centered on the life of Jesus. Two important points: to meditate is beginning prayer. There is much prayer beyond this, but meditation is how one begins. The second point is that meditation here spoken of, is Christian meditation. As you recite the prayers, you are thinking about the mystery proposed for that decade. For instance, the third mystery of the Joyful Mysteries is the Nativity. Obviously, you are thinking of Jesus' birth, how it came about, you picture the scene in your mind. But you also think about why He came to earth, why He is here, and how should it affect my life. In meditation, you consider all these things, ask God to help you and guide you, draw conclusions from them and ask God to help you live your life according to His Will. For instance, for every decade of my rosary, I usually start it off with something like, The Scourging at the Pillar: "Lord, help me to walk in Your footsteps, help me to know Your Father's Will and to do it; help me in this mystery to accept the pains in this life meekly and humbly without complaint or bragging, and to offer them up to Your Father, for His greater glory and honor, for the salvation of my brothers and sisters, and for my own salvation." Our Father...
Now, if we have all of that down, revelations to many saints through the ages have made know to us God's will, and that is praying the Rosary is a great way to grow closer to God, a great sign of predestination, etc. There is no way that sin can remain in your life if you are praying the rosary each day. If you are sincerely praying and meditating all the mysteries of the rosary, you will grow closer to God, grace will fill your life, and sin will leave it.
An excellent book, written by St. Louis de Montfort called The Secret of the Rosary lists many miracles and helps in this prayer. It is something that every Christian trying to lead a good life, conformed to God, should pray each and every day. Many saints refused to go to bed until they had finished their rosary. I find that a little beyond me, so I pray my rosary first thing when I get up in the morning.
The best way is to pray it everyday.
