Oil filter change vs oil change

I thought about skipping a filter change. I usually cut open the oil filters. My Dakota, i put 60k on a 4.7, sold it at 220k. My ram 5.7 ive had for 15k miles, 158k. My daughters cherokee 4.7, shes put 15k on it, 167k.

What ive noticed, when ive bought them they had cheap no name filters on them and had gunk in them. The oil was always dark. I alway use full synthetic. At the first change the filters had some black debris but nothing too concerning. On the Dakota i did 2 rounds of sea foam in the oil. 1st time scarred the hell out of me. Metal crap black chunks and there was a tic that eventually went away. Never did seafoam to my daughters jeep, hers burns not even a half quart every 5k. After a couple of oil/filter changes the filters seem in all the vehicles seem relatively clean. So I thought about skipping a filter change...but then if figure their only $8. Cutting them open has given me peace of mind...

(if you wondered, after the 2nd sea foam on the Dakota, just some black slime, more than usual. I waited a year or so between sea foam. Truck ran great.)
