I use the native Threading class, myself, largely because it's so easy
to switch to multiprocessing if the GIL starts to get in the way. YMMV
if you don't use CPython.

In all probability, your threads will spend 99% of their time waiting
for the network. This makes threads very effective, and largely
eliminates the GIL issues (if they occasionally have to take turns,
it's not going to affect things much). Pick whichever threading
library suits your coding style; they'll all work, most likely.
