Higher max theoretical throughput its an N750 (300/450) vs N600 (300/300) firmware I got was latest DEC 2012 mine was $11 more than this one

"N600, N750 and N900 all make the guarantee that simultaneous dual-band usage won’t impede the performance of any single network
. With N600, users get 300 Mb/s on both the 2.4 and 5 GHz bands. N750 ups the 5 GHz band to 450 Mb/s, and N900 gives you two simultaneous 450 Mb/s connections."
In realty as long as you are N600 or above you'll be happy... below is where you sacrifice by losing the simultaneous dual-band usage.
In most tests the 3600 performs the same as the 4300...but three antennas look cool
I never knew the "Nxxx" is the industry's standard when it comes to describing the specs of the routers. Cant wait to get mine today!
To buy, or not to buy: That is the question.
