which subwofer is better?

*JL Audio f113 or REL G1 and
*JL Audio f110 or Velodyne DD+10
This is a question you have to answer yourself. What someone else thinks is "better" might not be right for you. Sorry, that's just the way it is.
I have and love two JL110s and they are great subs. That said, I hear the new Velodynes are pretty awesome...
