Sorry - not real world as in I have used the stainless filters, but perhaps real world in terms of economics.
If I were doing a round the world ride, I'd use one to avoid needing parts in places where new filters might be a challenge.
Riding in North America or Europe, I'd stick to OEM filters for $8 ea (vs $70 for Scotts). Easier to change, and break-even on price is years away. Depending on how much you ride and how often you change filters, there won't be any savings unless you keep the bike for quite a few years.
So unless a) you believe the stainless steel filter is actually better at filtering, or b) you ride huge mileage, I don't think there is a case for one.
I use OEM single-use oil filters.
