If you don't have a Keysight 82357B, then I won't recommend buying one, the NI GPIB-USB-HS is much better.

Why is the NI GPIB-USB-HS much better in your opinion?

Better compatibility, more softwares will work with NI-Visa compared to Keysight Visa. For example, Python's PyVisa library depends on NI-Visa. Also, NI-Visa is much more stable compared to Keysight's software, Keysight software would randomly stop my software from communicating with my devices, no idea why.
However, in my opinion, both of them suck compared to the AR488 adapter as it does not need special drivers or software to work, its plug and play, at least on windows. Its also a lot cheaper ($8 to make one) and open source, and more stable, never had any issues with this adapter. Its biggest disadvantage is that most softwares that rely on a VISA library won't work with it. This means that the end user has to created softwares for this adapter.

I understand your fondness for the AR488. My reason for using the HP 82350 and 82357 is that I got them for --FREE--. :)
I was considering buying the parts for building the AR488's as I have more instruments to connect, but the command set seems to be different from the "standard" HP and NI commands.
What do you think of the xyphro adapter? ( https://github.com/xyphro/UsbGpib ).
It is based on the standard USBTMC protocol. This allows the GPIB test equipment to look like a normal USB based measurement device and work flawless with e.g. NI VISA, Labview, Matlab or PyVisa.
Cost is similar to build as the AR488 and is not tied to the Prologix command set.

Looking at the github page, the xyphro adapter seems like a pretty nice gpib adapter. I will try to make a few of them and see how they compare against ar488 and 82357B.

That's great, glad to hear it. I will be awaiting your evaluation. Thanks!
