7Dii + EF 100-400 L IS USM mark ii
IMHO, unless you mostly use a tripod, just upgrading to a modern IS lens will massively widen your shooting opportunities. I was sceptical until I did.
In forests I will need a tripod just with an IS equipped lens - 0.5 sec. exposure time @ f/11 and ISO 200 is a typical exp. parameter combination.
But there are other situations where I would like to have a 400mm lens WITH IS. So the new lens might a candidate - your experience confirms my liking of the new lens ...

(1) Fascinating. What are you shooting?
(2) The super telephoto lenses detect tripods and only use IS to correct mirrorslap - but I find the combination still useful for some subjects, especially the moon and planets.
(3) Why do you stay at ISO 200?
Ad (1): I like scenes in deep forests where you have the play of light and shadows. The shadows are DEEP so I need these long exp. times to get the DOF with a telephoto lens.
Ad (2): That's what I meant with "replacing 70-200 4.0 and 400 5.6": Just having one compact lens which substitutes two lenses I usually carry with me is a great option - if the new 100-400 delivers the quality I like!
It will help me too in situations where I have the tripod NOT with me.
Ad (3): I now shoot with APS-C exclusively - a matter of cost/availability of lenses etc. ISO 200 or a maximum of ISO 800 delivers the quality I want with the equipment I have: 40D / 600D / EOS M .
For bird in Flight ISO 800 - 1600 are fine because freezing the motion adds more detail compared to the detail loss by increased noise/NR - but: The EOS 40D AF is good but 1Dx or 7Dii might be a little bit better - so I haven't tried this field of photography a lot ...
