LUMIX DC S5II or DC S5IIX?

Hello everyone,

I’m currently struggling to choose between both of the models.

Currently I’m using a Canon EOS R8 to take videos. I use a Ninja V+ as an external recorder to record in 4K/60fps in ProRes. But have some compatibility issues.

So which of these two would be the better choice?

Thank you in advance for your help.
