The only benefit i can see with that radio is that it covers higher bands (3.8 to 6 ghz), so if you are implementing WIFI, or similar technologies it is better suited.
The FPGA is different and might be a bit better, but not too much, and that it supports “hardware expansion”. There has been talk about a hw expansion with the LMS8001+ ( Next Gen LimeSDR ). Maybe it will use SPI over the FPGA headers to reuse the FPGA and FX3-chip of the limesdr. Also analogue devices are a bigger company than lime so their brand might be more familiar.
