Did I...?

I could have sworn I posted a thread about whether or not there was a functional (rather than theoretical) difference between a USB 3 to Ethernet adapter and a Thunderbolt 2 to Ethernet adapter, but I can’t find hide nor hair of any such thread or poste even mentioned.
So did I actually post it and I’m just too blind to find it, or did I just imagine it?

It appears you did not. You've discussed thunderbolt peripherals, and done ethernet troubleshooting for members. But no real overlap.
Perhaps you posted in a thread where that discussion happened, or on a different board? If you didn't use the words "thunderbolt" or "ethernet" yourself, search will not find anything. If you only commented on others' posts.
Oh, and a TB -> Ethernet adapter ought to work better (by itself). As TB is serialized PCIe, the computer is talking to it like any other network card.
USB -> Ethernet adds a protocol switch. In practice, USB3 might be fast enough to absorb the conversion, and hide any packet latency. So maybe I don't know the practical answer.
Exception: if you use the network adapter on a TB eGPU enclosure, and you are using the graphics card too, all bets are off. A GPU card hogs the TB buss. I've gotten hesitations when playing video files from a USB drive plugged into an eGPU box. The hesitations vanished if I unloaded the GPU, or if I used a USB port on the Mac.

Well you've answered both of my questions!
Amazon has a nicely priced USB 3 gig adapter, but there are a lot of negative reviews from Mac (and some Windows) users, so I was concerned about wasting time messing with that sort of thing.

Any objection to moving this to Peripherals or Networking?

No. I think that might be useful. Even if Thunderbolt isn’t “all that,” its PCI nature makes it useful for a lot of things. This is a good example.

I'm just waiting for a few spare dollars to buy the adapter. I'll probably buy from Amazon...getting to the nearest Apple Stores isn't particularly convenient, and I can save a few dollars through one of Amazon's vendors.
