Do you think Ayumi has a strong voice?

So lately my mother has shown a great interest in J-POP music lately, her favorties being Koda Kumi and Namie Amuro. She didn't like Ayu very much, mostly because I told her she doesn't have an R&B sound. But I was determined to turn her into a fan xD;... So, yesterday I brought all of my concert DVDs, featuring Koda Kumi, Namie Amuro and then Ayumi Hamasaki. She LOVES Koda Kumi, she thinks she has style and her songs make you want to dance. She thinks Namie Amuro is a great dancer and also thinks she outshines some American artists by dancing AND singing at the same time.

Then came Ayu, I first put on one of my favorite perfomances, CDL 2005-2006 Bold & Delicious with the Gospel Choir (my mom's a religious nut xD; ). My mom was stunned at how strong her voice was and wanted to watch more and more and more. I even put on some of Ayu's PVs, JEWEL, Startin', and momentum (cause I loved her coat xD; ). She fell in love with Ayu's voice. I was really surprised that Ayu turned out to be her favorite so quickly. So my question is, do you think Ayumi's voice is strong? Did it capture your attention at your first listen?
