As far as my understanding, Sheikh Mahmoud Khaleel Al-Husary's Tajweed recitation is MOST ACCOURATE and Clean. When you hear the recitation you will be able to follow the Tajweed InShaAllah.

Shaykh Mahmoud Khalil al-Hussary (Arabic: ٱلشِـيـْخ محمُود خَلِيـْل الْحُصـري‎), also known as Al-Hussary, was an Egyptian Qari widely acclaimed for his accurate recitation of the Qur'an. Al-Hussary committed the entire Qur'an to memory by age 8 and started reciting at public gatherings by age 12. In 1944, Al-Hussary won Egypt Radio's Qu'ran Recitation competition which had around 200 participants, including veterans like Muhammad Rifat. The quadrumvirate of El Minshawy, Abdul Basit, Mustafa Ismail, and Al-Hussary are generally considered the most important and famous Qurra' of modern times to have had an outsized impact on the Islamic world.
