Fuji X-pro2 and X-E2. Anything I could do with a D7100 I can do with the X-Pro2. With the X-E2, that becomes almost anything with the compensation being lightness and compactness.

After size and weight the biggest plus to nearly any mirrorless is the accuracy of focus at wide aperature and narrow DOF is inherently better.

Speaking of Fuji the AF speed with the latest series X-T2 is as good as any DSLR short of the super-pro bodies like D4 and D5. Even the X-pro2 (not intended all that much for sports) is defiantly a step up from my old D7100.

buy the canon M5. Small, light, super sharp - the best AF among mirrorless.
You can buy a Fuji that costs double - and it is a good camera - but it is big and heavy. No one seems to ever mention that ! And Fuji lenses - which are also great, are probably heavier than larger lenses for DSLR's.

So if you are going mirrorless to save weight and size - Fuji and Sony are not the answer.

That's like asking if anyone uses a digital camera. Probably 80% of the cameras in use are mirror less. Are you interested in full frame, APSC, Micro 4/3, or compact? You won't get a meaningful answer until you ask a more focused question. There's a big difference between a Sony A7R and a Nikon V2, more difference than between the A7R and a Nikon D500.
