The 90D Overall is a better camera, but there are reasons to go with the 7Dii or not upgrade. The main reason, the lenses!
List of lenses on my blog that have enough Resolving Powe

EF 8-15mm f/4L FisheyeSee list of lenses below the video.
A couple side notes because of so many questions I am getting about this:
1. Many of these lenses have been confirmed in our FB group: Michael’s Canon 90D FB Group
2. If a lens isn’t on this list, I strongly recommend searching our facebook group for the name of the list to see examples: Michael’s Canon 90D Facebook Users Group
3. The general rule of thumb is that if it is both an older lens and a zoom lens, it might have issues. Older lenses mean the design of the lens is greater than 10 years. Most newer zooms and primes seem to do better generally but there are some exceptions.
The Canon 90D Sensor (and M6II) have a pixel pitch of about 3.2 microns, which means lenses used will likely need to have better resolving power than the list Canon Recommended for the 5Ds and 5DSR:
Canon’s Lens Recommendations For the 5DS and 5DSR. I have added a couple to this list that should have enough:
Confirmed = Multiple Users have demonstrated with images on our FB group
Unconfirmed = Verbal Only from different sources
50/50- Some good, some bad examples from the FB group, might come down to the copy you have or how stopped down your aperture is.
Italics = Likely /Likely Not (Depending on list) based on MTF Charts

EF-S 17-55mm f/2.8 IS USM (We’ve seen good and bad examples, does better stopped down & might come down to lens copy. I prefer the Sigma 18-35 1.8)

Third Party Lenses that Seem to be Working Well:
Wides:
– Sigma 18-35mm f/1.8 DC HSM Art Lens (Confirmed)
– Tokina atx-i 11-20mm f/2.8 CF Lens for Canon EF(Some users love it, but may have Chromatic Aberration issues)
–Tamron SP AF 10-24mm f / 3.5-4.5 DI II Zoom Lens
Normal:
– Sigma 17-50 2.8 (50/50 – Many are happy with it) ***DISCONTINUED*****
– Tamron SP 24-70mm f/2.8 Di VC USD G2 (Decent but, Much better stopped down)
Telephoto:
Sigma 50-100mm f/1.8 DC HSM Art Lens for Canon EF (Confirmed)
Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens for Canon EF (Confirmed)
Tamron SP 70-200mm f/2.8 Di VC USD G2 Lens for Canon EF (confirmed) – Though in two cases needed to be micro adjusted
Tamron SP 150-600mm f/5-6.3 Di VC USD G2 for Canon EF(Confirmed)
Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary Lens for Canon EF– We have seen both good and bad examples of it. Might come down to lens copy / if it is micro adjusted.
Sigma 60-600mm f/4.5-6.3 DG OS HSM Sports Lens for Canon EF– Ive only seen a few examples from this lens. One of the images was not good, the other was acceptable. Not enough data to say for sure either way. Super zooms tend to struggle more with very tight pixel density.
Lenses That Do Not Seem to have Enough Resolving Power

– Canon 24-70 2.8 I – (Not Great) ***DISCONTINUED*****

Primes-
– Canon EF 400mm f/5.6L USM – 50/50
Feel free to leave links in the comments that demonstrate good or bad samples and I will add them
I really enjoyed it, but this is a subject matter that others might not find engaging. Inventions, electricity, egos, entrepreneurship, history, Tesla, inability to navigate psychological obstacles. Awesome! A definite rental, but if you are fans of any of the above, you will appreciate it. Nothing else came out this week that I was interested in.
Here are my preliminary tests for Dynamic Range for the Canon 90D and M6ii (basically the same sensor performance wise) as they compare with other cameras. You are looking for a couple things:
1. The point where you can no longer see a distinct line between two of the numbers.
2. Artifacts that hide these borders as it gets darker.
3. Important to keep in mind 90D and M6ii are 32.5 MP.
Note- This is not an ISO noise test, which is something else. Most shots were taken at ISO 100, the XT3 was at 160. Color differences can usually be explained by WB settings.
Makes me realize how bad that 70D sensor was! 
Notice how much “cleaner” the 5D4 is, but all has streaking in the higher numbers.
XT3 was tested at ISO 160. 
I believe Sony’s 24 MP sensor is getting old now. It still has posterization issues, 90D does not. (Looking for black bricks between numbers) Sorry about the lint!
