n-strike elite darts VS zombie strike darts

So my brother just got a zombie strike doublestrike and of course it came with the zombie strike darts, so I wanted to know how they compare with elite darts. So I got some elite darts and the zombie strike darts, went outside and shot them as far as i could, (using the modded firestrike shown above) then ran over to see how far they went, and discovered that they both went the same distance.
I don't know if there is a difference between new and old zombie strike darts. My conclusion is that they are the same darts just a different color.
