I may not be best placed to comment as I don't have any Fuji experience to contrast/compare with (bar a Finepix model from years ago), but here's my three penn'orth.
I got my X-S10 a couple of weeks ago. I've had many cameras over the years from film Praktica's to Panasonic compact (TZ60) & bridge (FZ330) both of which I still have, Canon EOS DSLR (100D and 77D) neither of which I have now and several others in between. I consider myself someone who like photography as a bit of a hobby/fun rather than someone who is either any good at it, or as serious as many of those on this forum, but in retirement I'm trying to aspire to become a better photographer rather than a "snapper".
I bought the X-S10 after struggling to get on with my 77D which I found too big & heavy for regular use. After a LOT of research, mirrorless and Fuji seemed the way forward after almost pressing the button on a Panasonic or Olympus M43. I was thinking X-T30 but wasn't a massive fan of the retro body style and dials (I know, I know...shoot me down
) and then the X-S10 was announced and it seemed to good to be true, with a deeper grip, fully articulating screen and PASM as well as IBIS.
Anyway, I have it now with an 18-55 and 50-230. So far I love it. I'm slowly getting to grips with the settings and menus which feel more complex and have more depth than the Canon's. I was worried about the joystick having only ever had cameras with a D pad, but that concern has proven unfounded.
Overall, it's (relatively) light but feels solidly built, great to handle, has more settings than I'll ever need. I've seen views that the EVF is too small for some, but personally I'm fine with it, even as a glasses wearer. Battery life isn't fantastic, but I never go out without at least one spare. It takes seconds to change a battery, so whilst it would be nice to get more shots form one unit, it's far from the end of the world.
All in all, I'm very please with my purchase, and just waiting for some decent weather to get some really nice shots it it's pretty much been incessant rain and dark cloud in South Wales since I got it! A couple of sample images below. Happy to answer any questions about the X-S10 if I can.
