Personally, based on what I know Ethereum by far wins this one. Ethereum can do everything bitcoin can technologically wise PLUS it can already - act as the new decentralised "server" for all Developer applications - allow for certain existing and new currencies/blockchain to merge and integrate into the ethereum blockchain.Which then leads to - Dapps allowing IoT/smart devices that can communicate independently of each other( making stuff like auto selling excess solar power to neighbours/ drone delivery services / driverless car services/ airbnb auto lease services) - decentralised media outlets - decentralised identity database - finance decentralised international banking apps - realestate/automated inheritance apps/parliament voting list goes on basically anything you can think of as a business can be run on ethereum.
Though economically Ethereum is losing to bitcoin currently, its business adoption has seen far greater support than bitcoin. Ethereum is growing and being adopted by businesses from all industries and it's a matter of time before products are ready where average customers would be using Ethereum on a daily basis.
