Improving naval warfare
Man the Guns brings some features already developed for land combat to the sea, like new skills for admirals and "terrain" effects. The whole point in the expansion is the brand new design system for ships and fleets, that allows some specialization, mainly on small ships, as well as giving different "missions" to your task forces, reducing micromanagement this way. The only problem I have is that, in general, naval warfare doesn't feel as relevant as it should in game terms, so according to your play style this expansion could be an "overkill".
HoI4 DLCs usually give us new content for countries. UK and USA new alternate history paths are good enough. Opting for Mexico or the Netherlands (instead of countries like Spain or Turkey) may seem not so urgent but they're fine.
Man the Guns improves HoI4 overall, and it gives you some new ways to play the USA or UK. But it's a step below Waking the Tiger, as it's not as impactful.
