Depends on YOU the rider. Your riding terrain, the style riding you enjoy. The tires you are wanting to run. If you enjoy trails and will be sticking with a 26 or 27 inch tire it's a toss up. Tight rock trails and wash outs on 28's or so, then definitely go with power steering. The non EPS bikes turn very well (to me, not everyone may think so) compared to other larger bikes. The EPS is a great feature to have and has become very reliable. I hated the idea of it when buying mine(also wanted red..) I thought of it more as a problem than an assistance. Now having driven it for a solid day waking up the next day you can barely tell you rode the day before. Feedback is a minimum on the EPS models so that is also a selling point possibly, driving over rocks and fallen trees doesn't jerk the bars from your hands as it once did on non power steering bikes.
But again, it's all up to the rider, YOU.
