I found Berlin even better. Very cheap, great service (and they speak German and English), great connections, easy app (Google Maps shows it all as well), tourist friendly tickets, and the best of all: no mandatory NFC card!!

It also depends on where you live in NL. Every 10 min a train to Ehv is neat, and I got a bus from Ams to my home city every few minutes whole day long, but the rural areas don't have such luxury. The joke for the trains goes, that "they don't drive on time, they drive on rails."
