[Enchilada]

Northern Hemisphere is better because it does have southern observers bragging how much better their skies actually are... Also;

1) Northern Hemisphere (NH) has the Andromeda Galaxy, and some bright and large nearby independent galaxies
2) The NH has better planetary nebula Ring Nebula, etc.
3) Less stars making it easier to find you way around without confusion.
4) The best open cluster is Double Cluster in Perseus
5) Better Double Stars, and more colourful ones - due to the proximity of one of the Milky Way Galaxy's spiral arms.
6) A decent pole star
7) Constellation with a classical history
8) Has the best Constellation in the sky - Cassiopeia
9) Most variable stars have the class of variable named after them. I.e. Cepheus - Cepheid variables. Gamma Cas variables, etc.
