My experience with the RAT on occasion has been rather maze like as
well. I've always figured some thought went into naming it properly to
produce the appropriate acronym :)  Unfortunately I don't have any
suggestions for improving the pathways.

- From my perspective, as long as the routes can be followed reasonably
well, the RAT makes it easier to figure out what's going on--under what
conditions is a resource skipped, etc.

The real difference is perhaps more aesthetic. How do you want the
questions to appear.  In a .problem, all the questions will be on the
same html page, and depending on how it's coded, you could have have a
new question appear "between" to questions that have already been
answered, which might confuse students given your "looping" structure.
With the sequence, each question appears on its own page, and assuming
the logic is correct, students can reliably just hit the "next" button
to get to the next question, whatever that may be.

My 2cents.
