Question about buying soba

I went to the local Asian mart to get some soba noodles and while trying to research them realized that most soba in the states except for the money pit that is Eden foods is only around 20% buckwheat. I’m looking for a really buckwheat-y flavour for the dish im making so I’d prefer a higher percentage or just a good flavour in general— is anyone familiar with these two brands? They also had Hana brand made in China, which I didn’t snap a picture of. Any help appreciated, if this isn’t the right community I will cross post into a cooking subreddit or something.
