As a computer programmer, engineer, and someone who has bought more NIC's (maybe 10 wireless) and routers (5 routers total) this is what I can tell you:
You aren't going to get a clear cut concise answer. What you should get depends on your needs, and what your neighborhood is like.
If you FORCED me to cut it down to two recommendations I would go with:
Netgear N900 (a, b, g, n) 2.4GHz and 5GHz band (up to 450 Mbps) This has VERY favorable reviews on CNET and Amazon.
Linksys E4200 (Stay away from the EA model versions) (a, b, g, n) 2.4GHz and 5GHz 3x3 (up to 450Mbps)
The 2.4GHz band is VERY VERY crowded around most areas, and that often leads to poor speeds and reception. My neighbor had an old analog baby monitor that wreaked havok on my signal. You are also competing with your neighbors for the few open channels there are. The 5GHz band is relatively clear and empty by comparison.
But to benefit from this, you need to pick a NIC (network adapter) card that can also do 5 GHz. If the network card is listed to support a, b, g, n, then it will work on 5Ghz. (Reason being is a protocol is only available on 5 GHz band)
For a matching adapter I recommend the TRENDnet TEW-684UB. (a, b, g, n) 2.4Ghz and 5Ghz 3x3 (up to 450Mbps*) It's very small (about the size of a credit card) and has a solid connection in the 5Ghz band. However you'll never reach 450Gbps upload/download as USB 2.0 can only do 480Mbps, but in reality it's closer to 240Mbps with all the overhead.
With the TEW-684UB and a 3ft USB extension cable, I can maintain 200 speeds up/down all day in the 5Ghz band. I've only ever been dropped once.
If you still need stronger your options are:
1) Repeater (which slows down maximum throughput and they can be flakey)
2) Powerlien networking adapter
3) Creating a directional antenna using aluminum foil (very effective)
4) Industrial wireless (which can be THOUSANDS of dollars)
