Is DW better than SC as a Sub game?

[PhilM]

I got SC when it first came out, being a 688iHK player,
but didn't really play it, due to being distracted by so
many of the other great games in the world today.

I finally got round to re-installing SCXIIc the other day.

I turned down buying DW cheap at the local game store
a few months back(I will probably never see a copy again here
in Australia now), as I thought all the surface options would once again distract me from my great desire of becoming a "true"
Sub Commander .

So, which is the better "sub" sim.?
