This is an evaluation of performance on bands used for satellite communications, i.e. VHF and above. If anyone is looking for an SDR primarily for HF and below, I think the Airspy HF+ Discovery is considered the best affordable option right now. If you want a good general-coverage SDR, I'd recommend one of the SDRplay products like the one they reviewed or the cheaper RSP1A.
