Yes, the fastest advertisement wins the election and becomes master.

See above. advbase is a base time added to the skew. (+1 sec per base value)

On slower networks you need to use a higher advbase on both to account
for lag in local network equipment such as when the two nodes are in
different buildings or similar situations.

Typically, base matches on both and you set the skew to give your
preferred primary node preference.
