Several people have mentioned the "fun" aspect of shooting with certain cameras... for me, the Fujifilm cameras I've had - and still have - possess this quality in spades, and then some. My current favorite Fuji body is an X-T3 - because of how it feels, how it handles, its amazing (to me, at least) EVF, and the literal plethora of rather addictive (to me, again) film simulations available. Its predecessor, an X-Pro3, was equally 'fun' but felt a tad too large for me (I like slightly smaller camera bodies) as opposed to the XT3 which is almost my perfect size. The only M43 camera I had which came close to it in the 'fun factor' department was my late Pen F which I also must confess to really liking (though the Fujis beat it out in terms of their complex and intriguing colour renditions and recipes.
Curiously, the one other negative factor some have mentioned - lack of IBIS - hasn't truly bothered me. In practical shooting it simply means that in low-light or available light situations, I have to take care when shooting at slower shutter speeds - but, honestly, that reminds me of my film shooting days, so it's not a big deal. But (and there's always a "but", isn't there?) for those times when I really feel like I need IBIS, my superb small Olympus - an E-M5.3 - more than covers me.
So my solution is different cameras for different situations. Maybe not ideal for some, but it works for me.
Incidentally in spite of the recent irrational price hikes of the X100 series cameras, many of the earlier X-T cameras - including both the X-T1 and the X-T2 - are still superb cameras in their own right, and possess close to the full functionality of my X-T3 (with the single main difference of what the different sensors can accomplish). I also believe the X-H1 - another Fuji with a truly superb EVF, a compellingly nice in-hand 'feel' - and the one of the first Fujifilm X-series to offer IBIS - can also be found, used, for what seem to me extremely reasonable prices.
Obviously, different strokes for different folks, and we all have different small things which push our personal photography buttons - but in terms of the basic exercise of having a camera which provides a truly enjoyable and somewhat fun shooting experience, for me at least, Fuji delivers.
