Like the Honda GXV, the Chinese copies typically do have ball bearing crankshaft support bearings and iron cylinder sleeves, but parts availability can really be hit-or-miss. Who specs air filters for those? (Hopefully, it's the same as a common engine.) If you need a carburetor down the road, or even just a new needle or seat, where do you go?
Briggs has long been the market standard, and you can get Briggs parts pretty much anywhere you go. Honda parts availability is usually also very good, and their parts are very inexpensive. A genuine Honda carburetor is usually less than 30 bucks, for example.
Maybe it's a regional thing. My local OPE shop has all my Kohler stuff in stock all the time, I've never had to order a filter or maintenance part. Honda was always more of a mail-order proposition.
Also the original B&S V-Twins weren't Made-in-China Daihatsu license Engine blocks? They sheared so many flywheel keys and bent pushrods, they practically single handedly made Kohler the V-Twin standard of the OPE world. Since then B&S's experiments with plastic camshafts haven't exactly endeared the world to them, either.
Don't get me wrong, I love my many old B&S singles and parts are indeed cheap and available, if the price is high chances are Oregon or Stens has it cheaper. But I had several friends have their early B&S V-Twins [censored] out early, and it wasn't poor maintenance. Maybe they're better now but I have yet to find someone willing to take a chance on them.
