Thanks for your responses!  I am on the verge of getting the 90D.
Toni-a.  I like macro and telephoto more than "normal" photography, so specifically, birds, insects, flowers...stuff like that.  And I just like great detail in general.  Shots of animals where you get good detail.  that sort of things.

Thanks again!

About birds, 7D2 would make only sense if you want to shoot them in flight otherwise 90D or M6ii are the way to go.
M6ii plus adapter should be the same as 90D for your work while being cheaper and lighter (unless you count the batteries it will be eating and that you'll have to buy and carry

I was going to include the M6ii.  I think there are some trade offs, but the big advantage would be the tracking.  Even birds on the ground can move a lot.  But it's actually the form factor that I do not like.  I like the larger camera.  The other plus, I should check first, but I believe they have a wide angle macro lens for the M6ii that actually works!*** 

The cost, I think is about the same if you acknowledge you would need the to buy EVF and the to EF adapter.  And all things considered I don't want to assemble my camera+viewfinder+extra batteries and chargers+adapters. I think I like the concept of an aps-c mirrorless, but they haven't quite packaged it right for me. 

Anyway, I am feeling better about 32MP sensor.  This 90D actually has me just about sold!
