To the MP5 vs MP7 ergonomics is not a matter of being prettier to look at its a matter of being easier to handle, The MP5 has a full stock etc, making it easier to handle and sight with. As for range the range on both is about 200m. So thats not really an advantage for the MP7, but yes it has marginally higher ROF and holds a few more rounds.

To the ARX-160 vs the M4. They fire the same round, out of likely the same 30 round mag, at a range of 500-600m. So I have no idea what you on about.
