>>3415754X100S will only fit in a jacket pocket. I have one and I like it quite a bit, I throw it in the small pocket of my backpack and it's my EDC when the weather's iffy.
GR II is extremely beloved by street shooters everywhere, it's the best value by far at what, 600 bucks brand new? Haven't shot one myself -- I got an X70 instead for the articulating rear screen. I like the X70 a lot but I think the short lifespan left prices a bit elevated.
Can't speak to the RX1.
I'm sure they're all decent options but they all shoot differently, you have to weigh how you intend to shoot over the spec sheets.
