Actually most laptops (or desktops) can't compete with USB sound cards.
Because the audio chips that come on your motherboard:

 * are usually cheaper and lower quality;
 * often have limited kernel/ALSA driver support (which is why the alsa-driver 
bug backlog is always out of control);
 * often suffer from noise on the headset jack from the digital-to-analog stage 
being too close to the rest of the computer.

So I strongly recommend USB audio in general. Especially for wired
headsets where you can also avoid the lossy nature of Bluetooth audio
encoding.

And for Bluetooth audio, such a USB dongle sounds like a great
workaround for this bug. But we all wish it wasn't necessary.
