Oh it is, Ethereum is considerably more complex and ambitious, and is starting to hit its scaling limits as well (like any time a popular ICO happens the network bogs down). And their solution, transition to Proof-of-Stake + Sharding, is also complex. That's going to be interesting. If there's a first flipping, there could later be counter-flippenings. But Vitalik is an excellent community manager and has so far managed to prevent a major schism like in Bitcoin.
