AMS is great to get to and from because the rail link (under the terminal) is so good it might as well be in the middle of Amsterdam but it isn't, so the transport links in general for everyone who isn't going to / coming from Amsterdam are brilliant too.
It is spacious and has good shopping (and a casino, if that floats your boat) plus a good variety food and drink facilities. Menzies deliver baggage very swiftly and if you're watching carefully outside the buildings you can see that the whole thing is laid out pretty logically for such a large airport. The whole place is kept clean and tidy and the security people (who with the exception of the Schengen area, you'll sensibly meet pre-gate, not post-passport control) are efficient and friendly (as are their counterparts at BRS but the airside area there is just too crowded and the coffee shop too utterly abysmal for me to be able to honestly sing its praises).
I'm quite partial to Oslo Gardemoen too, which also has a frequent high-speed rail link under the terminal, as well as being well laid out etc., although check-in can be pretty hectic if you don't do the interwebnet thing.
