I use fish since the first time I tried it some years ago because it upgrades your user experience. I don't understand what the fuss with not being compatible with bash is. Bash scripts run with #!/bin/bash in bash. If you need to write/copy&paste some bash code just jump to a bash shell. In the meantime, fish will save you lots of time on your daily regular shell usage.
