CA Lorraine BR 5.7>5.3?

Hi everyone, I recently had the chance to play CA Lorraine. I can play this tank with a BR of 5.7.
For me, should I lower the BR to 5.3 or 5.0?
After being nerfed, CA Lorraine is practically unplayable in AB mode.

CA Lorraine has a good gun, But there was no explosion fuse.
It has slow reverse gear speed.
It has armor that only protects against the M4A3E2’s 75mm gun.
Thin side armor
It has no machine gun.
I think instead of playing Ca Lorraine, I’d recommend playing ARL44.

I hope my topic is useful.
