Let's be real here: none of these croc-likes are really good. Croc used the format perfectly because the plot was his daily, uneventful life. A retrospective of his character before his death.
All these formats with a goal fall flat on their faces because a) the majority of them are wish-fulfillment and b) this format doesn't work with a goal because you need some sort of plot that can be narrated outside of 4 panels a day. Hell, the last chapter of Croc was more than 4 panels because it explained more, not just because it was the ending.
In short, Croc's legacy is shitty, run-of-the-mill "otaku dates X" SoL's that suck.
I hope Croc's anime adaption will be good so it puts everyone in their place.
