FPComplete's Hoogle is a bit more complete: https://www.fpcomplete.com/hoogle

It's good overall but sometimes the ranking is weird. For example, if you search for "ByteString", what you'd expect is only the #3 hit.

For beginners who are likely to be searching for core libraries, the other Hoogle might be more useful.
