Are my Wireless N speeds high enough ?

Hi - first off I do a lot of downloading/uploading from my main PC but I don't want to use any wires from it to the router so wi-fi is my only option.

Right now I am using a D-Link Dir 655 ( ver. A3 ) with firmare 1.37NA - connected to a PPoE broadband of 100 mbps.
On my pc I am using 2 wi-fi USB adapters that I am currently testing:
- TP-Link TL-WN722N - 150mbps adapter with an external antenna
- Netgear WNDA3100 v2 - an N600 usb adapter
I have brick walls in my building and the router is located in another room about 20 feet away with a hallway and 2 doors in between but not exactly straight line.

Now, for testing these 2 adapters, I set the router to 2.4Ghz/40mhz and got on it.
First the internet speed tests.
With the Netgear - I get a connection of 216mbps confirmed by the adapter's software, although Windows says 242 mbps and the router says 280 with a 82% signal.
Using speedtest.net I got about 70 Mbps down / 43 Mbps up : http://www.speedtest.net/my-result/3161956083
Downloading a torrent file from a tracker that has mostly users from my country and my IPS - I can get a steady 9MB/s download speed ( so 72 mbps line ).
With the TP-Link I get similar results but the speed is 150 mbps as per Windows and 112 as per router with a 80%+ signal.

Second I thought that the best way to test the wifi speed is to copy some big files to my WiFi PC from another computer that's connected to the router via the Gigabit Lan. So got my laptop into the room with the router, pluged that sucker into one of the router's Lan ports and shared a folder containing some HD movies and start hitting it.

I am able to get a sustained speed of 15-16 MB/s with the NetGear and about 9-10 MB/s with the TP-Link.

Is there any point in trying to find a better router or considering my speeds, this is as pretty much high as it gets?
How are these speeds? What is the speed you guys can hit via a N Wifi network when trying to copy a large file from another computer ( considering that most of the internet lines in the world are nowhere near the speed the N Wifi can reach ) ?
I'm curious if 15-16MB/s is good enough.
My ISP has an even faster line solution for just a 7$/month more - a Broadband 1Gbps line ( you read it correctly - 1 GIGABITE internet line ) and since wi-fi is my only option right now, I'm wondering if it's worth the change. Can the wi-fi practically get faster than what my 100 mbps line is providing right now or the wireless option is bottlenecking my speed at the moment ? Would a faster ( N600/N900 ) router be any better. I know theoretically YES but practically things are always far from the specs.

Also one other thing worth mentioning, if I take both adapters and move into the kitchen which is a bit further away from the router ( 60 feet ) but with 3-4 brick walls in the way, the signal drops considerably. However now the TP-Link manages to do better, because of the external antenna I reckon and the antenna does make up for the bandwidth difference. The TPLink is actually twice as fast as the NetGear which is surprising and kinda makes me not return the TP-Link as I might find it more useful in the situations that I need a bigger distance reach, it was 12$ so ... not really worth returning it since it behaves so good when further away compared to other "faster" 300mbps adapters ( i've tested some others in the past ).

Thanks
 
You are getting excellent speeds considering the distance and building materials. The only hope for faster wireless transfers would be with a pair ASUS AC routers, one in media bridge mode.

I still find a way to rely on gigabit Ethernet, for consistent transfers over 850Mbps. Nothing else will keep up with gigabit Internet.
