Haven't experienced Nitrogen long enough to make a good objective
comparison. Just that there was something about Nitrogen Records, that
seemed -- verbose and intimidating. Also, found it somewhat difficult
to imagine how that syntax maps to the generated HTML. On the
contrary, I found ErlyDTL very simple, once I saw the CB
video-tutorials on youtube. Also the MVC constructs were a bit easier
for me to follow in case of ChicagoBoss. The admin-interface was
dead-simple. Finally, I found the tutorial for ChicagoBoss to be
short, to-the-point, very simple/lucid and achieved something concrete
I understood. The documentation get me functional quite quickly, and
in fact, there wasn't very much to read. While it might take a lot
more to become an expert, I felt that I could get up-n-running (from
zero) with CB much sooner.
