Oh sure you can get Atheros based wifi adapters like the TL-WN722N but they tend to be bulky and best suited for use in a desktop. If you want something that takes up less real estate it's pretty had to find anything with Atheros - Realtek seems to have the market cornered here. For example there's the TL-WN725N nano. This little gem works great with Windows but until recently it failed spectacularly with Linux. At first it didn't work at all. Then you could download the source from Git, build the module and install it. However the next kernel update put you back to square one.
Now with the latest kernels the TL-WN725N works right out of the box, If you are looking for something much smaller than the big Atheros wifi adapter, this might be the one for you. Mine is version 2.1 and it's running well with Linux Mint and MX-16.

I use this one for my Pi. It has a realtek chipset but it does support monitor mode and works with linux out of the box: EDIMAX EW-7811Un N150

Those little nano adapters are great IF your computer is not too distant, or have too many barriers (walls, floors, ceilings) between the computer and your WAP (wireless access point). But if distance, barriers, or other sources of interference are, or might be a problem, I recommend an adapter with an adjustable exterior antenna.

For PCs, I much prefer Ethernet. But if running a cable to the PC is not practical, I recommend a PCIe Adapter like the Dual Band TP-Link N900. Dual band helps to avoid congestion. PCIe avoids the hassles that often come with the USB interface. And the exterior, adjustable antennas help ensure the best reception on both ends. And with detachable antennas, you can even position the antennas up high, if necessary.

I keep the small USB adapters around for use in SFF desktops that might not accept a PCIe based adapter. Given a wider full size case and an available PCIe slot I would go with a dual antenna setup - and I have in my main Linux desktop. Wifi does a good enough job in my house that I don't need to run cables. The Windows desktop that sits right next to the router has an Ethernet cable.

Ethernet is definitely the way to go, if practical. Not only do you totally eliminate reception issues, Ethernet networking is inherently more secure. But often punching holes in walls, floors and ceilings is not practical so wifi may be the only viable alternative.

I just did a couple of bandwidth tests and I was geiing 43 Mbits down on wifi N downstairs in my basement through a wooden floor. That is plenty fast enough for anything I'd want to do. On the wire next to the router I'd get close to 185 down on a good day.

I have one Raspberry Pi with the Edimax nano setup as a WiFi access point. It is pretty stable as Linux is. Love this.

Of course  the WN725N Nano works great with Windows 10 as you would expect.
My Lenovo Flex laptop has a balky Atheros internal wifi adapter that drops connections all the time. I shut it off in the BIOS and plugged in the WN725N. It's fast and reliable and doesn't take up more room than a typical wifi mouse dongle. It would be great on old laptops if you want to upgrade to N performance.

It drops the signal randomly. It's a design flaw in the chipset I believe. Driver updates have never fixed it.

I have decided to give the internal wifi another try in my Lenovo Flex2-15D laptop. I have taken a new suggestion to disable Bluetooth (the adapter is a combination of wifi-N and Bluetooth.) Also I have a new gateway and no longer use a wifi extender network which may have confused things. So far the internal adapter seems stable. We'll see.
