French here, sliced bread is like "the worst thing ever".And dont get me started on industrial bread.If your bread isnt like less than 30 min fresh,hot from the oven, you shouldnt eat it.And by the way,we call sliced bread "english bread".
Dutch-near-German-border here. I think your opinion stems from the quality of industrial bread in France. If you look in the Netherlands you'll find a wide variety of very tasty pre-sliced industrial bread, always fresh baked in the morning.
That being said, I always buy unsliced artisan German bread from my local baker who imports it from across the border.
And for fun, let's fan the flames a bit. You can't compare the simple french baguette to the rich flavour of artisan German bread, simply no contest ;)
Dutch industrial bread is nice in its own way, but it's not really bread like a baguette is. White Dutch bread has a cake-y character to it, which goes very well together with more 'delicate' toppings like butter & hagelslag (chocolate sprinkles), jam, a young dutch cheese or boiled ham, which are common in the Netherlands. Whole wheat sourdough bread, no matter how great, just doesn't mesh with delicate toppings like strawberry jam. That said, a baguette or artisan bread is a far superior base for a good old cheese, Serrano ham or other 'strong' toppings. This is why brown dutch bread is never worth buying IMO -- it's kind of a weird thing like cake made with whole wheat flour that reminds me of antroposophic foods: it's slightly less unhealthy but it tastes like crap. If you're gonna eat something unhealthy it better taste good.
American here. Several years ago, our son was working in the Netherlands (west), and met us for a few days in Paris. He took back a fair bit of bread, not liking the Dutch product. To be sure, I have had good locally baked bread in Lower Saxony.
In my childhood in northern Ohio, there was a local bakery that had its own slicer and would slice the bread on request. I remember the product as quite good (I preferred the rye), but growing boys will eat pretty much anything.
