Your experience will depend very much on which Terminal you're at (there is a big difference in age and layouts of individual terminals) and, in particular, whether you're forced to switch terminals when transiting.

A good airport for transiting into Europe, and in my view usually more pleasant than London, Frankfurt or Paris, is Amsterdam Schiphol.

Agree on AMS. The construction there has been going on for a couple of years and it'll be nicer once that's done, but even with that, it's my preferred airport to connect in EU.
