Decided to upgrade router to Netgear R7000 AC1900 router due to good newegg deal and I tested the speeds on iPhone 5S, 13" Macbook Pro and Hackintosh Desktop. I used speedtest.net for all measurements. Tests were done in Phoenix, AZ with Cox Internet in apartment complex (lots of interference). I tested 2.4 and 5.0 GHZ for all + Powerline on Hackintosh
Some errors to point out - for some reason forgot to test 2.4GHz on Asus N66U DDWRT
First going to start with Netgear R7000 - DDWRT 23550M-R01
|  | 
| Hackintosh 2.4GHz | 
|  | 
| Hackintosh 5.0GHz | 
|  | 
| Hackintosh Powerline | 
|  | 
| iPhone 5S 2.4GHz | 
|  | 
| iPhone 5S 5.0GHz | 
|  | 
| Macbook Pro 2.4GHz | 
|  | 
| Macbook Pro 5.0GHz | 
Next Netgear R7000 Stock - V1.0.3.24_1.1.20 (Latest firmware)
|  | 
| Hackintosh 2.4GHz | 
|  | 
| Hackintosh 5.0GHz | 
|  | 
| Hackintosh Powerline | 
|  | 
| iPhone 5S 2.4GHz | 
|  | 
| iPhone 5S 5.0GHz | 
|  | 
| Macbook Pro 2.4GHz | 
|  | 
| Macbook Pro 5.0GHz | 
Lastly, Asus N66U with DDWRT installed
|  | 
| Hackintosh 5.0GHz | 
|  | 
| Hackintosh Powerline | 
|  | 
| HTPC LAN | 
|  | 
| iPhone 5S 2.4GHz | 
|  | 
| iPhone 5S 5.0GHz | 
|  | 
| Macbook Pro 2.4GHz | 
|  | 
| Macbook Pro 5.0GHz | 
I then put all the data into Graph. For some reason stock R7000 2.4GHz were much faster than others. I rarely use 2.4GHz and the options of DDWRT are necessary for my setup so I will stick with DDWRT on R7000. I don't have any AC devices to test that function yet.
