Interesting the first link says thicker iron plating, the second link says normal tips are too thick and it has thinner plating (0.5mm).
I have one Ksger black used daily, heater coil resistance is closer to a genuine T12 (~7R). The generic tips tend to be ~8-8.5R.
Although I haven't had any problems with regular generic tips other than one DOA.
If you are a hobbyist I would just get a selection of the regular clones, then if one dies from use or has any issues, replace with genuine T12 or taiwan type.
