Compare Two Netgear Nighthawk 1750 Routers - Edit

Hi,

I've got this on my home network, and it connects (depending on time of 
day) about 11 devices which include cell phones, laptops and desktops, 
android and iphones, tablets, and printers.  Both bands are active.  It 
works fine.  This is it.

I need to replace an old Motorola Surfboard b/g/n router at another 
location.  I was going to get the same Netgear AC 1750, above but then 
saw this:

For either router, especially at the 'new' location, I really don't care
about QoS or parental controls.  All I really care about is providing 
the highest possible for the user's network card.

Is there a significant difference I should care about with the second 
listed router, above?  It's half the price.  I don't much care for 
Amazon, but that's where I found it.
