Well I would run the champs lab filters first, with the Delco being preferred. Of the Fram and Microgard, I wont run either, but if I had to I would do the Microgard since its cheaper and essentially the same filter as the Fram, just less overpriced for what it is.
Now I would run an old Microgard over all of them. They were pretty good filters made by Purolator.
