I got one of those NBN when they first came out years ago,good call,but I never did care for them Zink BIG's it came with.Throw a set of any other guts in it and it was a totally different sounding(better range and tone) and running call.
I would like to try a COD some time,seems it has better reviews then the other two calls you listed.
