UFM Fuji Super

Which branch is bigger?

Branch 1 (Sukhumvit 33) or Branch 2 (Sukhumvit 39) ? Or do both have the same amount of products?

And is it worth a visit to stock up on snacks? Or do they more or less sell the same stuff as Donki?

Their website is down, that's why I'm asking that second question here.

Thanks!
