What do you use each race's shields and engines for?

I’m curious to know which roles you assign to the various engines and shields in the game.

Personally, I prefer using Terran All-round engines on capital ships (L and XL), Split combat engines for fighters, and Paranid travel engines for my civilian ships.

As for shields, I always use Terran or Teladi shields for the ships themselves, while I use Split or Paranid shields for components.

As you can see, I never use All-round engines (on S and M ships), and I’ve never used Argon engines if I could avoid it.

The question is: what use cases do you see for the other engines or shields—the Argon ones, for example: For role X, I always use, or like to use, equipment Y?

Note: I’m not interested in roleplay-based answers (like playing using only Argon ships and equipment); the idea is that you have the freedom to use all equipment without limits (without mods, in the vanilla game).
