I haven't used jeweler's compound. But, I think most compounds for jewelry ('soft' metals like gold, silver, etc.) are made with abrasives that aren't as hard or aggressive, such as iron/ferric oxide, aka 'red rouge'. Anything too hard would carry the risk of stripping gold/silver plating off, or otherwise removing too much precious metal, too fast. The Simichrome and Flitz polishes are made for steel (at least), and they utilize aluminum oxide as the abrasive. Much harder than 'red rouge', and therefore much more effective on steel and other 'hard' metals. It's not necessarily coarser than rouge; aluminum oxide can be found in particle sizes down to 1 micron or so. But, definitely harder and works much faster, to a very high polish.
