More dynamic but about what?
Transaction speed, block time.
Value transacted per second or transaction per second.
Ethereum has faster speed and more dynamic with gas price but transaction fees are not cheap even that blockchain is more dynamic than Bitcoin.
Bitcoin network is more secured than Ethereum network. They are all good blockchains and BTC, ETH are good to invest but if you need to find a better, it is BTC.

Ethereum's two-tier and three-tier technologies are becoming more and more mature. The opportunity of industry transformation still lies in Ethereum's layered technology. It should be proficient in two-tier and three-tier technologies as familiar with bitcoin technology. Bitcoin is very stable and unchanged. It is the best investment. But I think Ethereum is more fun.
