And a second vote for this!
I have an Analog Discovery as well, and am using it through the Real Analog course (Digilent's name for their Circuits 1 course) and it is really neat. I have no professional gear to compare it to, and I can tell it is limited to purely educational use, whether as part of a class or self-education.
Since it is a Xilinx FPGA inside that implements most of the custom logic, there is a notion that maybe it could be redesigned and reprogrammed to provide additional or different functionality, still making use of the input signal conditioning and sampling circuitry.
