If you have a spare PCIE slot i would recommend this. I have it and it works great.

Most the USB cards will have similar performance. A PCI card is not any faster mostly because you are limited by the wireless speed well before you hit the limit of a USB. 802.11ac is the only exception and USB 3 ports are now a option for those too.

The key is to match your router. If for example your router only supports single band and only runs at 150m it does not do a lot of good to pay extra for dual band and 450m.

I tend to like USB adapters that have longer cables so you can place them on top of the machine. You of course can use a USB extension on any adapter. The key is to keep it away from the metal case if this is a desktop.

Which brand is mostly a personal choice. All the major cards are very similar in performance.
