I believe that its not the best but rather the largest and most well established decentralized platform right now. Don't get me wrong, the Smart-contract which the Ethereum offers is a game changer and still being widely use and acknowledge, a true game changer in the cryptocurrency. The only downside is that the prices of the gas right now is really high which I hope will be corrected soon.
I believe that a full-fledged transition to the second version of the cardinal will reduce the commissions within the network, and we get even more profit by burning these commissions, and then the value of Ethereum will increase even more.
You're right on that one, a full-fledge transition will definitely improve the value of Ethereum, I just hope that improving and lowering down the value of the Gas will be part of it. A transition we're all waiting for and looking forward to.
