Joshua C, are you just sounding like an opinionated 14 year old because you are? or are you just a biased weapon owner?
On the 416/417 If you read up on the changes, the only thing kept was the trigger mechanism(and perhaps one other part). And for your information, the AK-47 is a very unreliable weapon that nobody uses, the AK - 47M is the proper and correct name for the well known AK, the original variants of the AK were jam happy peices of ****.
In terms of an assault rifle, a few things matter, reliablity/accuracy/stopping power. The AK has two of these to about 300 Yards, the H&K has all three to a much further distance (depending on your weapon sights, be they open/aimpoint/ACOG). It depends what you need, if you only need a weapon out to 100Yards max, both will do and its up to opinionated twats to yell out which one is best, if its a matter of range, then H&K wins.
EDIT: Thought it necessary to throw in that the H&K inst necessary my most supported weapon here, there are many AR's that can engage up to 700-1000 Yards. Just making the point that the AK series suffers from the lack of very effective medium range accuracy.
