In practice, personally I prefer SPI due to the tendency of cheap I2C devices to lock up the bus and not respond to the semi-standard reset protocol. This necessitates hacky workarounds to power-cycle the device via a GPIO for example. SPI is more robust in this sense due to the devices reliance on a falling edge of CS to clock data in rather than have a truly shared bus as in I2C. Performance-wise also, SPI can be orders of magnitude quicker than I2C.
