20 mm Rats Turmoil

Let’s talk a little bit about the 20 mm rat tanks around rank 5. We already have 4 of them; the American XM800T, the German Wiesel 1A4 and Luchs A2, and the Japanese Type 87 RCV (P). More could be added, from several nations - Israel might be one of them - but that’s not the topic, although I would certainly like it if you would post your thought of what similar vehicles we should see in the future in the replies down below.
I am here to talk about their BR: the German ones are sitting nicely at 7.3, the Japanese - at 7.7 and the poor American XM800T is all the way up at 8.0.
All four perform similarly and are used the same way, so I suggest to give them all the same BR - probably 7.7, a nice little spot in the middle.
I would also like you all to share your opinion about that.
Thank you!

The 87 and especially Luchs are boats compared to the Wiesel and XM, and the Wiesel has a very limited traverse and is unstabilized, they are all at appropriate BRs
