Right, for me it would be the X-E3 which is lighter although considering my sizeable hands it wouldn't make much difference. I've held the Fuji and it felt well-balanced with the 18-55, and my thumb fitted very well indeed, no buttons to be touched inadvertently!
I like to carry my camera with a handstrap but that worked fine even with my relatively heavy Canon dslr and 24-70 i used to own.
I have yet to try the fuji in actual use, so can't comment on that yet.
However, considering my current photography interest and sales, i might be better served by the Olympus EM 5 ii and its in-camera stability and high-res mode. It is one of the few other cams that produces nice ooc color, has good magnification VF, and Olympus obviously has photography at heart.
The thing is: the 45 zuiko seems to produce a beautiful image paired with these M43 sensors, and appears to be sharper than what Fuji produces with Xtrans and the 56. I believe that even the X-A3 with the bayer sensor produces sharper results, but it doesn't compete at higher iso and has no VF.
I really liked the Fuji when i first saw it, the minimal design appeals, the left side VF is helpful. But it appears that Fuji is now also asking a premium for the camera incl the kit lens for no other reason that it can. (T20 and E3 body only is the same price, but with the lens it's 100e difference).
And of course, none of the RAW converters can process that Xtrans correctly, which isn't my initial concern but is something to keep in mind.
