Design wise I've always liked:

Flametongue
Durandal
Morningstar
Doom Mace
Euclid's Sextant
Tournesol
Masamune
Orochi
Dragon Whisker
Gungnir
Rod of Faith
Wizard's Staff
Perseus Bow
Artemis Bow
Aldebaran


In answer to the OP's question, I really like using axes and maces, and I love equiping Penelo with a big arse measure on account of how cute she looks.
