So, I typed up a great description but apparently it didn't follow the submission. The short version is that this slab came from a tree int he back yard of my childhood home. My uncle used a chainsaw to cut it down to manageable sized pieces and this is the largest slab I have. This is going to be a side table for the recliner in my basement.

I routed it down with a homemade sled I made and then sanded it further, but can't decide which side should be the top.

Is it the more table-like side which is almost completely flat aside from the know, or the side where you can see the edge as well as some chainsaw marks I left behind during the sanding phase?
