I wouldn't be surprised if ETC gains more popularity for adhering to the decentralized principles but I have no idea who is at the helm in terms of development for ETC.
ETH has seen a tripling in their value in the last few months. Definitely, the platform is a serious one, with serious goals and isn't a "shitcoin" (1000+ coins that fork bitcoin and pump and dump). They have buy-in from some major/bluechip players in the tech industry.The creator of ETH has stressed that ETH is a new technological experiment and volatility is part of the norm. So don't throw your life savings into it.
