Agree with you, ETH is better than ETC due to community adoption, level of development that is ongoing and in true value. Most ICOs are on ETH (and some on BTC), not so much on ETC or any other coin for that matter. ETH is also better in tech than BTC. Long term, I think ETH has a better proposition than BTC, though BTC has first mover advantage and will continue to benefit from that in the short to medium term
