Thus, if using a library that is prone to triggering horrible error messages when misused is compared against using another library this does not trigger such error messages when misused, the choice is clear.

But the way people avoid the hard to read error messages is to move
the error detection to runtime, where it is easy to control the error
messages.  Unfortunately, error detection at runtime is usually much
less thorough (as it is both hard to do and people don't want to incur
the cost in correct code) and hence much more expensive.  The choice
is between hard to read errors found early vs. (typically) much less
thorough error checking found later.  To me, the choice is clear, in
that I want to find as many errors as possible at compile time, even
if those error messages are painful to understand and compile times
are noticeably increased.
