Focus II, is a better quality ARF kit....only no hardware.... but, the workmanship is better, covering etc.

Flying: Depending on flying style probably. I prefer the looks and flying characteristics of the Arresti III .... (it is a very solid, tough and large airplane that tracks and presents extremely well.) I really fell in love hard with the Arresti after I flew it. You should also be aware that the Focus II flies great and the weight tends to be about a pound less.

My opinion is that you really can't go wrong either way.... Primarily, looks and budget are going to be your determining factors.
