ECLIPSE SW6123.4 vs. PIONEER TS-W126DVC

[bigdub_diesel 10+ year member]

ive heard a lot of good things about both these subs, but i have never acutally heard either of them. I wanna get 2 12's of one of these brands. Ive got 1000 watts to work with, so if i get the pioneers, ill get dual 4s and have 1000 watts on them, and the eclipses will be single 4s and will have 600 watts on them. Im mostly looking for SPL. Im buying on ebay, and they are pretty close in price. Anyone have an opinion or some input on these?

Here are some links to get a better look at them:
