Well, SR200 might have some extra 'endurance', but I do not know why some simple Tracks like 230 would have that ...
You know, about the moulds, I could agree with you if we were talking about something like B:D : there are notable differences, but they look the same, the production codes mean nothing, and you do not necessarily get a guaranteed good or bad one from either company. However, with F230, except what I would call weird exceptions, you can predict with certainty that TAKARA-TOMY's orange F230 will be great, the brown one will be decent or quite good, Hasbro's red will be hideous, and Hasbro's orange will be passable or good.
