I think that pole of player is great and wins the vs for those reasons :
Pole of Player gives lots of HP and lots of DEF.
You can do damages with both of your elementals with Pole of Player.
You can't really attack when you wear a SS+0.
Finally, a SS+0 gives more DEF but not a lot more and Pole of Player gives more HP than the SS+0.
