Rows or Groups?

My classroom is set up in rows, but I assign seats based on student groups. This way students only need to turn their desks to meet in their group. I change up the groups/seats each unit and sometimes have a set rotation when there is an activity that would benefit from hearing multiple opinions. 

My principal has been encouraging the switch to tables instead of desks, but the school budget will make that a bit of a slow change.
