Both aren't really like-for-like comparison, considering how much more kits are fitted on TfL-spec buses. We won't see a real comparison until Go-Ahead London's EHV-class enter service over summer. My rough guess is the E400MMC-bodied version shall be about 100kg heavier than the Gemini.

一直都搞唔清楚 Volvo 7900 plug-in 版
同 E350 Virtual electric 版有咩實際分別
係咪只係車頂插電同埋車底無線叉電既分別？
(諗緊係咪無線叉電效率比集電弓叉電低呢)
The pantograph 7905H you are thinking about is the Electric Hybrid - plug in hybrid is different in that it has a socket for charging in depot overnight. Charging method is currently the difference between the 7905H and E350HVE, although I recall reading from some source that, Volvo is open to adapt the B5LH for wireless charging as well (in response to the E400HVE due in London).
Wireless charging is not, in relative terms, not as efficient as plug-in or pantograph. Doing this through electromagnetic influence involve a bigger energy loss. The problem ADL faces, if true, could be down to the charge pad being not efficient enough.

有啲位我覺得幾突兀, 譬如擺電嗰個位, 零零舍舍用預製組件包住
倫敦版可能無咁突兀
This is no different to the Wright-bodied version though. In fact, I expect the London-spec version to have the battery moved forward at the same place as that on the Geminis, in order leave space for the rear door.
Personally, I quite like ADL has moved the battery pack further back. It makes the low floor space a bit more open.
It looks like the StreetDeck and B5TL weighs almost exactly the same. Both demonstrators with Go-Ahead London has a weight different of 60kg in StreetDeck's favour.

I am not surprised, given only so much can be done to take weight out of the bodywork. What is interesting is that it looks like the B5LH chassis itself is also lighter than the diesel E40D. Against the E40H, it is almost 400kg as well. Now I know that the E400s have a slightly bigger engine, which weighs more. However the difference is still quite startling.
Small wonders that the Volvo hybrid is selling so well lately.
