I was on team dynamic for a long time and have moved to team static.

For any long-lived code base, dynamic piles up invisible problems over time.

It's great for short-lived throwaway stuff, but as soon as you know you'll be maintaining a large code base for a long time, the "easier" part of dynamic actually becomes harder than just spelling stuff out.

It's obviously a trade-off and not everyone agrees, but that's my personal experience having run large eng teams for both types.
