That depends. RBREGS reflects register contents when the program or
SVC was called; TCBREGS reflects the most recent register contents for
the task. If you're taking a dump then TCBREGS for the dumping task
will reflect the operation of ABDUMP or ABEND, which is not likely to
be of interest to you.

RBREGS is not the *current* register contents.

Unless it's looping in an SRB, Type 1 SVC or Type 6 SVC. Also, see the
note above about the dumping task.

That's a different question, because you don't have extraneous SVRB's
complicating the situation; RBOPSW and TCBGRS.
