Which region? It makes a difference sometimes how the locals view your realm. The solution I would always suggest is both. Yep, how convenient.
But it's true, if you want a newly acquired region (Judging by your avatar I will assume you are asking about Braga) to regain stats faster, you'll need a concerted combo effort. Full estate coverage, knights of that region with police units doing normal police work, courtiers surveying admin, diplomats praising realm, heroes telling tales, lords/judges holding courts. Sounds involved, sure, but in a realm like Sirion, there is bound to be at least one courtier with free time, and one diplomat with nothing better to do than praise the realm. And if a lord asks his knights to perform some police work in their region, they better do it, or risk getting the boot.
Very true. But if you have limited man power and just need to hold onto the region until other resources can join you, Realm Control has in my experience the greatest effect in preventing a rebellion.
