Can’t go wrong with Tokyo manji tho
No clue about weeb stuff but maybe the white jacket is best because it looks the best and is simple and if "team walhalla" doesnt ring any bells then it could just be any brand and not even weeb related. Black jacket just looks kinda weird and too edgy to my taste also some who don't know what is says might think it has swastika in it unfortunately. And the hoodie is just something I would never wear personally, but maybe it fits your style. Could work as home clothing but wouldn't use outside.
As I said I have no idea about anime or what these jackets are but I like the white jacket the most even tho it might not be as versatile piece. Black jacket is the most versatile when it comes to outfits, but its bit weird and something I could have weared when I was younger.
