I work with my cousin who farms on one side of me and my brother-in-law / nephew who farm on the other side. Cousin has a John Deere and uses net wrap. BIL has a couple New Hollands, no net wrap. We don't see much difference in spoilage but my BIL definitely rolls his bales tighter and that may make a difference too. I have no problem spearing my cousin's bales but need to have good momentum when I spear my BIL's bales or I push them along. The net wrap is a pain. No matter what we end up with some in trees, some carried around by deer who get it stuck in their antlers, wrapped in my rotary cutter, etc. in addition the net wrap mechanism has not been trouble free. The net wrapped bales sure are good looking though if beauty counts.
