Whats your budget, and what do you want to take pictures of?
Based in spacs and price, the sammy looks best. I dont know sammys iq.
For $150 more, you could get an rx100 mk1 that should spank the rest of those in IQ, and still be small.
For the same price as those, you could get the EOS-M with the 18-55 or 22mm. AF is a bit slow, but the IQ will blow away those pocket cams, but the M is bigger than a pocket cam of course.
The LX7, as others have mentioned, should also be considered.
So, if you can spend the money, move up to an rx100 mk 1
If the budget is set, but you can do a bigger camera, look at the eos m
If the budget and size are limitatons, include the lx7 in your search
If the lx7 is out for some reason, try the sammy
Just MO of course
