I don’t know about you but for me it’s day and night difference!
Nashk seems more formal, balanced and good size.
FYI, my wife next to me agree too 
I’ll run some screenshots through some people on my social circle and I’ll feedback.
As for Kufi, it’s a nice font, but not suitable in my opinion, it’s more Art than font.
I have a HiDpi screen, so I’ll do more extensive testing tomorrow.
Thanks
