Your battle stats, how strong your hired allies are and your price....I believe anyways...somebody correct me if I'm wrong.
battle stats. build stats. Allies. Hire value, and a few other things that aren't fully known/visible.
Depends on your playing style as to Hansel or attack, I like attack as powerful and can defeat most people
Guild Hansel is by far the fastest way to grow, but you sacrifice a lot in stats for that plunder. If you don't mind having low stats for a while while you buy up all your land, then I would go that route. I'm not that patient though. Attack build is the second fastest way to go, and SoS Hansel is the slowest of them all.
Attack builds do better in lb as it is easier to strip farm a Hansel. So if you want to be on the lb be attack and have millions of dollars
