AXIOM PRO 9 vs AXIOM 12

I need to decide which AXIOM to install on the Cockpit.

AXIOM PRO 9:
I like the idea of the HybridTouch controls, specially if I am caught on the rain outside

AXIOM 12:
I like the big screen that I can read from any helm (my boat has dual helms and the MFD goes in the Cockpit table) and easier to see all the AIS boat + Radar on one screen.

1-What are you thoughts?
2-Is it possible to fully operate the touchscreen of the AXIOM on the rain?
3-What's the power consumption for my sailboat (no sonar).

Thanks,
JP
