Did you forget brother deoband is the centre of the world. Having said that, I do have to agree their lots top notch deobandi qaris, I myself was taught arabic and quranic recital by deobandi ulama. There also very good barelvi ulama with good recital. Id say that none of the groups are superior than the other. You will have good or bad from both groups. As far as bangladesh is concerned some of the best qaris are produced by the madaris of Allamah Abdul Latif Fultali Al Naqshbandi-Mujadidi-Muhammadi-Jaunpuri who is neither barelvi or deobandi. PS To Maudh Khan Rai-Barelvi and Barelvi are not in same division let alone being confused as being one an the same town, rai-barelvi is in Lucknow Division.
