One is optimized for getting past HR and screeners. It should check the boxes the job posting has, and leave out anything that indicates your age, unless they specifically ask for 10+ years of experience.
The other a longer, more detailed one to hand your interviewer during the interview in case they want to talk about specific experiences more.
Either way - you're always gambling here. You can't read the personality on the other side of a job post. Even if that job post looks like the best dev manager in the world wrote it (and that may be the case even) it doesn't mean that applications don't go through the screener who's also handling the hires for janitor, marketing rep, and help desk. It could also be going directly to that manager, and they may have a preference for detail.
I too have multiple resumes - in pdf, odt, txt. I simultanously keep them up to date and consistent so that when the recruitment system has obnoxious requirements I simply copy paste into the fields from the txt version. One is simply unable to win this game.
