The obvious difference is that in this one, one elderly person (who was always single) regains their youth, setting up harem hijinks.
In the other one, the elderly couple regains their youth simultaneously, setting up heartwarming moments.

It was a very different path from the very start.

I think this one isn't to bad of a story, sadly they dropped the manga.
