How can mechanically outdated stealth games be brought up in a discussion about the best stealth game of all time? That's like asking "is Gran Turismo 2 the best racing game of all time?", well obviously not, because since then there have been games that have provided better, deeper and more responsive driving experiences than GT2. The same can be said about the best modern stealth games when compared to the ones mentioned in the OP.
And given that you don't know me nor the games that I have or have not played, I think that you should keep all of that "kids these days" bullshit to yourself.
