That's not a fair comparison. In your example, you're talking about the average of developers in a language. In this situation, it's specific developers choosing between languages. Having the developers you already have choose language A or B makes no difference to their code quality (assuming they're proficient with both)
These are statements these developers will make themselves. They will say they don't like more strictly typed languages because they feel constrained and slowed down in development. They will argue that the performance hit is worth the trade offs.
