For myself, I use the following option:

https://mirror.guixsd.org https://mirror.hydra.gnu.org

I suggest keeping only one of mirror.guixsd.org and
mirror.hydra.gnu.org.
I don't know the story, or which one's preferable (I forgot m.g.o
existed), but both point to the exact same server. Hitting (and
caching?) the same box twice is probably bad news for both of you.
I choose 'berlin.guixsd.org' to be the default because it seems
to build
substitutes faster than 'hydra.gnu.org'.
I share that impression.
