I have found the interface more intuitive than the two Fuji X-E bodies (and more Fn buttons), actually, and that's unexpected. OTOH, the G6 body is not waterproof, but I do not need that presently. I will take an image of it with the Oly pancake (which for video and small jpegs is a 34 and a 68mm EFOV; how madly handy that will become on set). The package is amazingly compact yet, as you say, button placement and operation is a piece of cake.
No re. the batteries: different to G-7's (quite a bit bigger) and not the same as the GX1's either. OTOH, this means easy recharging at the end of the day, because I can change all batteries at once. Now that I have this body and the GX-7s side by side, I am really surprised that the G6 has not got more traction in the market. With its all-metal body the GX-7 feel more solid, but the G6 is lighter and yet feels really well made. I am selling the two Fujis today (the video—there's no comparison). And price-wise there's no comparison, yet the sensor is identical (I just tried the peaking function and it works perfectly, though I find the magnified view just as effective for me, and that's another advantage over the GH-3 for legacy lenses, I feel).
Perhaps later this year I will get a FF mirrorless, but the only Sony that grabs me (RX1) does not have a built-in viewfinder and the clip-on ones don't work for me. IF a Sony RX comes out with a built-in finder (even if its 2cm taller) and a 45–50mm lens, then I will reconsider.
