I like Haskell in theory, but: just to get a hello world takes a lot of CPU and disk space. The standard library is full of exceptions (you can use a different prelude, that opens a whole different can of worms). The ergonomics of converting between the thousand different string types are awful.
So, you being basically me, I have some recommendations:
Idris (2): good stdlib, has dependent types. A beautiful language. The compiler is self-hosted and bootstrapped by lisp - very elegant! The ecosystem is basically nonexistent though.
PureScript: also improves on Haskell in many ways. But, it's more of a frontend language, and though you can do backend, you're stuck with JavaScript runtime. Oh well.
By the way, the number of partial functions is base that throw compiler warnings is increasing, for example:

I hope it will increase further.
