Ethereum is a much better place to build apps and tokens. The ERC-20 standard has been game-changing. Currently 19 tokens at $100M+ market caps, with more to come.
Ethereum has the developer mindshare and tooling today, no doubt. But ETH also has fundamental scalability problems which are pushing out smaller value transactions. The team behind CryptoKitties for example left to develop their own chain that scales better. My belief is that UTXOs and the Bitcoin model are going to be simpler and more efficient at representing state and state transitions because it can be done locally and on one chain, rather than globally and sharded across multiple.
Agree that today, Ethereum transaction fees are terrible. But I'm quite optimistic for the future. First we have Layer-2 rollups: https://ethereum.org/en/developers/docs/layer-2-scaling/. Even setting sharding and rollups aside, Eth2 and PoS rather than PoW should give a significant boost to transaction throughput. I don't see bitcoin competing in that domain, it's taken on the role of "digital gold" rather than "world computer".
