Corral or box trap?

Hey guys I need your opinions real quick.

I used to have a small corral trap out in the woods and this place is a kinda swampy area. If I dig about 2-3ft I start to see water coming out. And also the ground is not even either with bunch of acorn trees around which also give me hard time to drive t post into the ground due to the tree roots. Do you think I should go with box trap this time? If I go with a box trap I was gonna make it 4ft wide and 8ftit long rectangular shape with side opening door which I used to have on my previous corral trap
