Mom told me not to talk bad about folks... (Waves)  
CAN Lisk be better than Counterparty? Sure, sometime in the future; but as of RIGHT NOW... Lisk is NOT READY.
I know because I run a dozen Lisk servers, am an alpha tester, and I asked Oliver, Max, and Isabella about it.
Isabella did some testing in behalf of ICN on Devnet. It is possible if a private network is created between Iconomi and exchanges, but some updates would need deployed to the main network, and would need tested on both devnet and testnet first.

or.... Counterparty is stable and ready.
