In my experience, your first dev will have four thousand ideas and experiments on the go, and leave an absolute mess in their wake.

And your second will be struggling to clean up that mess while also getting their own work done.

Of course, you expect the same level of work from both of them, but because person two has to do a bunch of person one's work as well as their own, person one ends up looking better and gets praised by management.

I'm totally not bitter at all.
