Well, I doubt any of us went to that school, so you're not going to get a direct answer. On the whole, I have heard bad things about schools that focus in game programming, but that some of the ones that offer Masters programs are actually ok.
As for something that makes "absolutely sure that you land a job after your graduation," I can safely say that none of them will provide this guarantee. The only things that would "guarantee" you getting a job in the games industry right out of school are personal traits (you know, ambition, motivation, etc.), that I doubt any of the schools you listed would provide any more of compared to a different school. All else being equal, the only real leg up a school can give you is the credibility and prestige that it has. For instance, a Masters graduate in CS from MIT is more likely to kick your ass, all things being equal, than you as a graduate student from any of the game programming schools you listed up above. Simply because it has that reputation.
If you want more specific answers, you should actually contact the schools to see what the success rate of their graduates are in getting hired as a game programmer, as well as contacting the places that you want to work, and seeing what their opinion of these schools are.
