Thanks @joeyarnoldvn.
I think it is important to compare crypto projects that are similar. Bitcoin to me is a store of value, a method of payment and whilst not perfect in terms of fees and processing time (when compared to Bitcoin Cash or Litecoin), it is still much better than the current SWIFT system banks use for most international transfers.
Ethereum is effectively a blockchain operating system allowing people to develop blockchain based applications. Similar to EOS, NEO and Cardano for example.
Therefore, to me, comparing Bitcoin to Ethereum would be like comparing USD to Android, so I don't favour one over the other.
