As long as it's a Gigabit adapter, they're honestly all the same speed. I bought the Plugable because it was recommended by lots of others, has great reviews for Switch use, it's affordable, AND it's USB 3.0 compatible. Works perfectly btw, perfect size for the side plate.
The Hori/Nintendo one is more expensive (more than double the price) and doesn't have 3.0 capabilities. Now that doesn't matter right now, but people believe that the Switch console is also 3.0 capable, they just haven't provided an update to "activate" it. If they ever do, and there's any speed increase to be seen, you won't get it with a 2.0 adapter like the Hori/Nintendo.
I read the reviews and they say it does work? it even says compatible with switch in the items title. Maybe im seeing a different one? This one is the first one on the page for me.
