I don't think there's much comparison between the percieved reputation of top UK unis vs top Dutch unis, but if you can see past that, and accept that Holland offers some excellent universities (relative to the continent) I think it becomes a no-brainer.
Second language, internships, reputable university (I hope!) and debt free...
Vs getting caught up in the RG bubble here in the UK and sacrificing your salary for your education. Of course, I'd look where (geographically) you want to work after uni, and see what prospective firms value (as ultimately, it's about getting a job).
