Otis and/or Pro Shot. For conventional sectional rods, Pro Shot (and their handle) is the best I've used.
The only value of the cheap USGI copies are their rods. Not as part of a cleaning kit, but just a couple sections taped, zip tied, or rubber banded to your handguards for an emergency rod to punch out broken brass or a severe jam. I think they're actually brass but with a subdued coating.
