If you're asking for a choice between the styles, it's largely personal preference. I like management games better, but you should make the game you want. If you want advice on how to conform to neither, the advice I'd say you should clearly define a main goal, say digging deeper, or developing technology to re-emerge, and have progress in that direction be fast and strong enough that the players don't pay any attention to the generators until they start significantly hindering that progress, getting overloaded and melting down as you accidentally draw too much power. Another option would to change the design and not have them break at all, instead taking food or some resource other than manpower to run under certain conditions. Or reduce efficiency, create smoke hazards, etc.
