Length
Longer Mast Extensions
Many Europin mast extensions start at 0cm and go up.
More extension length is avialable for sail rigging.
This means less masts would be needed to rig all your sails.

Sand / Dirt
Good
Europin extensions have tighter tollerances leaving less room for sand and dirt to escape.
Rigs left in the sand can sometimes get stuck together when sand is jammed inside.
Best
US Cup extensions have more space for sand and dirt to escape.
Connection Fit
Best
Tollerances are tight. The metal connections wear slower than metal.
Good
Looser tollerances - plastic wears faster.
Uphaul Rope
No Option
Loose uphaul rope has to be tied off or tucked into the sail rope pouch.
The upside is, the rope is available to make adjustments on the water without disconnecting the rigs.
Space to hide uphaul rope.
This option is great if you like to keep your rope tucked away.
