800mm f/11 because a cellphone isn't long enough!

Good comparison. I own the Sony, the Canon's predecessor (the 100-400L II), and am considering the Canon 100-500L.A quick comparison between the Sony FE 200-600 f/5.6-6.3 G OSS and Canon RF 100-500mm f/4-7.1L IS USM

As I stated above, the Sony is a G lens, which is a step down from the Sony "Grand Master" lenses. The Sony is more comparable to the Sigma 150-600 S or Nikon 200-500. These are long, heavy, wildlife-specific lenses with a lower build quality than either L or GM lenses. Weather sealing will not be as robust if there is any at all. The 100-400 (or now 100-500) lenses have much better build quality, the fastest and most accurate AF available, and should survive rough handling a lot better than the sub-$2000 long zooms.
I love my Sony 200-600, but the IQ at the 600 end falls a bit short of the best primes (not surprising). if someone came out with a DO or PF 600mm 5.6 prime with the IQ of Canon's latest 400mm DO or Nikon's 500mm pf, I'd definitely would go for it. I expect the 100-500L to have the best 500mm IQ of any non-exotic. I would not be surprised if it came close to the IQ of the Nikon 500mm pf (albeit 2/3 stops darker), which is excellent indeed.
