I think Ben Boxer is fine as he was in Kirby's run. At first I was very interested in this KirbyVerse thing that some writers have pushed for, but now I think that turning Kamandi or Ben Boxer into some kinda of OMAC variation and adding New Gods to the mix is rather restrictive and limited. Sure, nothing wrong in saying that Kamandi, OMAC and New Gods are happening in same "continuity", but they can (and I think should) represent different corners of this universe without interacting much with each other.
On the other hand it is likely that Pope has used up most of his Kamandi's ideas for his Battling Boy.
I somewhat doubt that Eagleshman could do such high quality for whole series. Now I can't say for sure, but I feel that this story had some of the best pages he had ever done.
