As these are no materialized views, but ordinary albeit dynamic performance views, they don't, as any ordinary view, 'contain' information. v$... is btw a synonym on v_$, so yes, they do provide the same results. Currently I can't recall why those two sets of names exist. They must have been starting with v_$ and then have realized this was awkward to use in more or less frequently used sql statements.
