I've never had a problem with Schipol myself. In my experience baggage loss is more related to airlines than airports.
About 10 years ago I worked for a year in various European countries flying out on Monday morning in a Suckling Airways Dornier from Southampton airport to Schipol, for onward connection. I carried my bags across the tarmac and "checked them in" at the bottom of the aircraft steps where the handler would place them straight into the hold. "Reclaim" was the same way at the bottom of the steps at Schiphol.
We had a huge number of flights for staff over the year but I think I was the only one who never lost a single piece of baggage. Easily the worst was the (thankfully now defunct) Belgium airline Sabena who managed to lose every piece of luggage entrusted to them.
