These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
It's the Same, Now It Sucks: The band itself got some flak initially for essentially (literally) being Versailles with a different vocalist. The release of "Blessing of the Future" did virtually nothing to quell this notion, being musically similar to a lot of Versailles music, but Classical Element, with its Progressive Metal influences and other experimental elements, quieted them down a bit.
Tough Act to Follow: Since Versailles were a popular and acclaimed band, a lot of people treat Jupiter as a successor to Versailles. While the members insist that Jupiter is a separate band completely unconnected to Versailles, and that their music should be judged on its own merits rather than being compared to their previous output, the fact that their lineups are 80% identical means that the comparisons are inevitable.
