A good developer uses the best tools available, because she/he knows the value of using them.
I do disagree with that statement "Ain't nobody got time for that." If you are going to spend 3months working on something, it's worth learning to use a new tool that is best for the job.
Also, as we are talking about web development, what is best tools? ASP.NET? Rails? Django? Go? J2EE?
