It would be a worthwhile trade-off, if those were the only two 
options available, but they're not. There are multiple build 
systems out there that do correct builds whilst being faster than 
make. Being faster is easy, because make is incredibly slow.

I didn't even find out about ninja because I read about it in a 
blog post, I actively searched for a make alternative because I 
was tired of waiting for it.
