Tank steer while stationary

Why do tanks (e.g.Leclercs, Leo2s) turn much worse stationary compared e.g. to the T80s even if they have neutral steering and the T80 havent.
To make this worse, when you want to turn with a tank equipped with neutral steering and then immediatly turn into the other direction, the hull somehow gets a kick into the original direction and therefore delays the turn into the new direction. This makes no sense to me at all.

edit: tested how long it takes to do a 360° turn for some tanks with similar hp/t ratio:
with neutral steering: (Ariete AMV, Leclerc Azur): 10s
without neutral steering: T80U-E1: 6,5s
Shouldnt the tanks with neutral steering turn better?

I guess it has something to do with the fact the T-80 can just send full power to the left or right track whereas neutral steering needs to be slower due to one track needing to be in reverse

lets assume this is the case, why would anyone then built a tank with neutral steering? Why would you take the more complex transmission into account if the turn rate gets worse?

Benefits for close quarters maneuvers. Theres nothing that actually stops a tank with neutral steering for executing the other form of turn as far as I’m aware, but turning in war thunder isnt modelled properly either. Its significantly simplified. The turning radius of stuff like the Sherman and all that should be much much worse
