I personally like all styles, but one thing that impressed me many years ago with the game of Gears of War 1, was to see that the polygons of the armor they used were not really High Poly but the textures applied were of a High Poly model.
This gave the sensation of incredible quality and with fairly simple polygons.
Something that I would really love to learn would be the application of these techniques to obtain detailed objects, but in models with few polygons.
I think that in order to use low poly it must fit with the style of play but personally I prefer to think of complex models with an optimization in polygons and that can visually seem of better quality.
