These are the basic features for a prospective buyer (like myself):
price: ~ $300
HackRF One is an open source hardware platform that can be used as a USB peripheral or programmed for stand-alone operation
operating freq: 10 MHz to 6 GHz
supported sample rates: 8 Msps to 20 Msps (quadrature)
resolution: 8 bits
interface: High Speed USB (with USB Micro-B connector)
power supply: USB bus power
software-controlled antenna port power (max 50 mA at 3.3 V)
SMA female antenna connector
SMA female clock input and output for synchronization
convenient buttons for programming
pin headers for expansion
supposedly ~50mW TX output

Airspy is a very tiny (5×3 cm) software defined radio receiver
capable of sampling 10MHz of spectrum anywhere between 24MHz and 1.7GHz.
24 – 1750 MHz RX range
3.5 dB NF between 42 and 1002 MHz
ADC @ 20 MSPS (80dB SFDR, 64dB SNR, 10.4 ENOB)
Cortex M4F @ 200 MHz and up to 204MHz with Multi Core MCU (dual M0)
1.5 ppm clock
1 RTC clock
External clock input (10 MHz to 100 MHz)
10 MHz panoramic spectrum view with 8MHz alias/image free
IQ or Real, 16bit fixed or 32bit float output streams
No IQ imbalance, DC offset or 1/F noise at the center of the spectrum
: SGPIO, 2 x ADC channels, 2 x programmable clocks
supposedly temperature-frequency stable
Wouldn't the HackRF benefit from a metal enclosure (instead of plastic)?
What are the practical uses of the extension ports (both units)?
What uses are in the GHz frequencies?
