I use the Madinah Mushaf. I used to use the 13 liner and it was good but it isnt in my opinion good for a hifz student memorizing a set amount each day. Since the pages dont end with an ayat its harder to have a the same amount of Quran per day. Whereas in the Madani Mushaf there can be a consistency in the memorization as brother Khaldun said,
Thats because if he does a page a day without ever leaving it, he'll finish in around 600 days.
I prefer the madani mushaf over the others. Though ive seen a 17-liner mushaf designed specifically for hifz...
