Hi Rowan!
Very Nice review!

I fully agree with your conclusions about the kit. Here's a picture of the finished model...

Dave, I can say that the Hasegawa model is a least more detailed than the Tamiya one. I didn't built the Hasegawa Kurogane yet but I have the kit. There is also an engine included but the hood and the doors are not seperate which is a shame (in both kits). The tyres are also very different . Finally I prefer the way Hasegawa did the canvas roof because in the Tamiya kit you have to use some filler to hide the construction seams.
There are two figures in the Hasegawa as well as an artillery scope, a light machine gun and an infantry rifle. This makes the kit more suitable for military modellers.
To sum up:
You want an easy kit? Pick up the Tamiya version.
You want more detail? Choose the Hasegawa one.
