Piston pin retainers?

After dealing with the wire-type circlips used on Mahle pistons as well as the fat wire circlips used on JE's, I can't help but wonder why other retainers aren't used that are easier to remove and replace. Are the wire circlips superior to internal snap rings? Surely it's not just to save a few pennies. (BTW, years ago I helped my late father overhaul an airplane engine in the home shop, and those big 5 inch pistons used internal snap rings to retain the piston pins.)
