I'm 43 and probably slower in the sense that I'm slower at producing code.
I'm slower because I think more about the code I produce. I have a wider knowledge of the domain I work in, cross cutting concerns, and technical choices that I'm taking into account when producing code. So I arrive at a more-correct solution faster.
I would say the tradeoff is worth it, but of course I would because I'm not in my 20s. If faster while missing more security issues, performance problems, and corner cases is what you want, my 20 year old self is probably better.
