Should I use V$CACHE or V$BH to determine the contents of the buffer cache?

I've been searching trying to find a script that would tell me the tables and indexes in the default  buffer cache.  The main script I found uses the V$BH view.  However, when I use those scripts, I don't see any blocks from a particularly active table being queried.  If I use the V$CACHE view, I can see millions of blocks.  Upon doing some research, I found that the V$BH view shows "pings" to the buffer cache, not really the buffer cache contents.  It seems the V$CACHE view (shows SGA contents) would be the more accurate way to view the contents
