Transmitting the written-in-arabic Quran is different than copying hadith. It carries a different level of purity. That doesn't mean that all hadith are wrong, but the key is that if there is a discrepency between hadith and Quran, then the Quran is the authoratative source.
And no where in the Quran does it say to read hadith. That would be absurd, because the Quran contains everything.

Our masjid/camii never even mentioned the words Sunni or Shiite. I still don't know which I and my family are, though it's been over 20 years since my repentence.
Do you know what Hidayat is? It is in the first ayat of Baqarah, and is the meaning of the first Beatitude, and is what the Quran is, and is the single most important concept in life and, therefore, the Quran.
And, yes, Sufism is the truest form of Islam, for we understand that love is the sole purpose of religion, even when and especially when dealing with evil-minded folks. Just remember that calling oneself something is a lot different than what one actually is. There are a lot of people calling themselves a "man of God" who are far away from Its Will to Love.
The Greatest Command (the Gospels being from God, too) is to "Love God with all your being, and then to love your neighbor as yourself." No form of religion that disrespects that command is living in the light of God's Truth. That's why the Sunnis and Shiites are warring while the Quran states explicitly that breaking into sects is prohibited. This is because hypocrisy and ignorance are but two of the 19 vices of the human heart that we must overcome to become fully submitted to the Divine Will.
God's judgement always looks into our heart, because that's where the truth is found. You should be more humble and respectful and open to learning new truths, because no one ever traverses the fullness of what can be known in one lifetime.
Learn about Hidayat, the nefs and the Ruh, and how love is all that really matters, in all our doings. I have given you the link to the truth of love and the Quran and how to navigate this life. Peace be with you. I love you. I am at your service.
