Which Is Best Starter Nation?
It is nice. If you are on Easy mode and do not attack anyone. Nobody will attack you for a very long time. Enough for you to research everything and gain good Diplomacy with neighbours, up to Alliances with both of them.
Any of the rebel factions I’d argue are the easiest. You start with such a huge army you can conquer half the map in 20 minutes.

Once you took a region in a week and use the resource to replenish your troops, the rest neighbors were just free to take, the rest of the country too.
