Sure the MC has the plot armor of "luck" and slightly impossible "foresight". And since he knows the "game" inside-out he can make the perfect builds and find the perfect places to go to next and strategies to use. But he's not overpowered like so many other isekai MCs that go way beyond the realm of common sense in that world.
He strategizes based on team composition, makes good gear and build decisions, and still quite often has one hell of a though fight. So much better than "oh yea I'm just so overpowered it's obvious I'll win anyway."
