If it is about the collaboration of Gothic idols, I would prefer — Yurika & Lily, then Sumire & Shirayuri twins & Alicia. As both Yurika & Lily have deep singing voice, while Sumire & Shirayuri twins & Alicia have higher pitched voice.

Btw it disappointed me that the songs of Shirayuri twins doesn't sound unique & Gothic at all, rather they were similar to some common Jpop. Also, no Gothic idols with deep voice in Friends is another thing make me disappointed.
