I wouldn't be in such a hurry - right now x265 (as far as I know the best HEVC encoder) still loses to x264 in terms of practical use (you only really get better results by using bitrates so low that the end product will look terrible anyway, and x265 loses hard to x264 quality-wise when encoding at similar bitrate and speed). Considering that x264 is backed by about a decade's worth of development, this isn't that surprising.
