Meh. Unfortunately I haven't really used any of those two, but Kuhn-Rikon is going to be much easier to find and maintain (e.g. spare parts for a pressure cooker) here in Europe since they're a Swiss company. That to me already decides between those two.

If you're open to other ideas, try and take a look at Paderno. They're a brand catering mainly to professional kitchens, so they can take a beating.

I have a couple of their pots, and they're really quite good. Including a little 3-ply saucier pot which I absolutely love because the steel is almost non-stick just by itself, perfect to make sauces and minimise the risk of burning.

You'll find their stuff around (e.g. Amazon) or on their web store, which ships within Europe for 5 to 15€, depending on countries. Not too bad for bulky and heavy pots.

Edit: I actually have a pair of Kuhn Rikon kitchen shears and it's really great, though it has molded plastic handles so likely not BIFL.
