No manipulation on my part. When I was in studio I was shocked to see such a difference. When I used my X-T20 previously I found the same exact differences in exposure.
I'll have to say I "feel" that the Fuji forum is loyal to their brand. I get it......... I use what works and this is why I own both still.
Personally if I was completely casual I'd be a dedicated fuji shooter. Huge variety of excellent glass and image quality to be proud of. For fast paced events I virtually miss shots with my X-T2 with EF-X500 flash. The heavier Canon gear I find I seldom ever miss a shot unless it's my fault in missing the focus point.
At the end of the day the difference in ISO from Fuji is not a big deal. My gut feel is that when you say iso 6400.....it's not. However as long as the shot is relatively clean...that's all that counts.
I don't have any brand loyalty, period. I've jumped ship so many times at this point I'm an avid swimmer. If Canon/Sony/Nikon/whoever comes out with a camera with similar controls to my Fuji at a similar price point but is in some way significantly better for my needs I'll probably jump ship again... but I haven't seen it happen yet. 
I just don't blindly follow the word of others... ever. If I don't observe something to be true first hand, I don't assume that it is, I want verified and cross referenced proof, any claims I've seen about Fuji "fudging the numbers" on their ISO settings has had an equal number of people with posts like Bobby's which show no difference what-so-ever. In my own experience I've witnessed no difference either... ever, and when I did it came down to either differences in how the shot metered or how the RAWs were converted. I see a big difference in exposure just from switching the camera color presets in LR, especially when going from Adobe RGB to any of the Fuji Film Simulations.
As for AF...
Genuinely; please do us a favor and keep some of these missed shots next time to share with us and try to remember what your in camera settings were. I'm genuinely shocked at how often you state the Fuji's AF is under-performing when I myself seldom ever have issues and I use some of their slowest and oldest lenses (18, 35/1.4, 18-55 and 55-200).
I concede that I'm very used to using single point AF and manual focus (I shot for over a year with nothing but MF lenses on my 6D) and also usually shoot slower moving subjects so my needs may very well be less demanding than yours, but I haven't heard literally anyone else on this forum or others complain about the X-T2's AF to the extent that you do, so I'm genuinely curious. Heck, I never even complained when using my CDAF only a7S, in fact I found it's AF to be pretty darn decent most of the time and flat out awesome in the dark (something I do occasionally miss with my X-Pro2, but I'm talking f1.8, 1/60s ISO25,600+ dark).
