These brandable marketplaces are not worth the effort.
I have made a few sales here and there with them. But I have made more sales on AN network, so does the others. Just keep an eye on the domain sales thread. There are few other reasons I have stopped listing with them. It is their algorithm so there is nothing stopping them from pushing their own listings. 30% + commissions are almost a steal. Even if someone lands on your name their system will always flash the "relevant names" which takes your lead instantly away.
If you name is good, it will sell on its own, regardless of the platform.
