I have only owned two so far (don´t have as much time to play as I used to): Seregios and White Monoblos. The Seregios one is cool because it stops bouncing, and the W.Monoblos has some good defenses for a part of G-Rank, but it has Demonic Blessing and you need Monoblos Hearts to complete it. Dunno about you guys, but this is STILL one of the hardest materials to get for me.

Also, like Pike said, Stygian G is good too.
