Question on camera for concert video for social media

Hi! Sorry if not allowed, but wanted to ask.
Tonight I'm shooting a concert (Alfa Mist) for a social media recap. Previous concert recaps I shot on a Sony a6700 and iPhone 17 Pro (depending on context). I also own a Sony DCR-SR15 and was thinking of using this one for tonight's recap, since it fits the vibe more (in my opinion). The concert is outside, starts at 9PM - around sunset - and it'll gradually get dark.

Any pointers? Would you shoot everything on handycam? Do I ditch the idea and go for the a6700 instead? Or combine the footage of the two cameras (in that case, how?)

Cheers, thanks for the help!
