This has been a matter of discussion amongst Muslims for ages, ulama supporting any of the 2 have concrete proofs, however the times we live in, the Ladies (especially modernist girls/women) are more inclined towards wearing Hijab rather than going for Niqab (If they are ready at first place) , the western mind set looks down upon noble women wearing Jilbab in its true sense (i.e. Niqab).
Note: Technically even Hijab refers to Proper covering from top to bottom, but here It will be referred for those who are not convinced with Face covering.
Some scholars have tried to reconcile between both viewpoints by offering choice to women whether they like to go for Hijab or Niqab (though Niqab is recommended), some like Nasir ud-din Albani have even gone to the extent of justifying that ruling on Hijab supercedes that of Niqaab, this according to us is a wrong conclusion, especially for our sisters in sub-continent where men are often seen preying at women (so in any given condition, anywhere in the world where the women may become easy targets of men satisfying their inner lustful desires, then the ruling of Niqab from merely recommended changes to Wajib and there indeed is proof of it rather a dominant one)
