From where I sit I would say the chains are about shot on the Komatsu. Just because there's little wear on the outer bushings doesn't mean that the pins are not worn badly internally. It just seems to me that the adjusters are stretched out a long way. I'd say it's closer to 30% than 100%... the pads are also getting that thin/bent/beaten look they get on old worn carriage....
I don't know enough about the respective machines to make any more meaningful comment about them.

When you look at the bushings that ride the sprocket... just because you don't see wear on them... doesn't mean the pin that is internal to that bushing isn't worn. Particularly if you're dealing with a SALT chain. Seals can dry out on the pins, lose their lubrication and wear the pins out on chain that has very low hours and consequently very little other carriage wear... just because he machine sat and dried out the seals.
Those chains looks rather stretched to me from the angles of the pics I see...
