In Arabic, Ayaatur-Rahman means 'The signs of the Most Gracious', or 'The Verses of the Most Gracious', and this phrase is found in the Qur'an - Surah Maryam (Mary) (Chapter 19 verse 58):
ุฅูุฐูุง ุชูุชูููููฐ ุนูููููููู
ู ุขููุงุชู ุงูุฑููุญูู
ููฐูู ุฎูุฑูููุง ุณูุฌููุฏูุง ููุจููููููุง
'When the Verses of the Most Beneficent (or the Most Gracious) (Allah) were recited unto them, they fell down prostrating and weeping'
All of the Quran is the word of Allah, and therefore it is all profound, and these videos are not meant to imply that any part of the Quran is better than any other part of the Quran, rather these videos are merely recitations that I like.
Similarly the reciters are all brilliant in their own unique way. I am not posting these videos so as to make them some above others, and Allah will insha'allah reward them their due.
We all have our own tastes, and these videos are nothing more than mine being expressed. Jazakullah
