I remember a couple of years ago using an excellent website where you could select any two cameras and see a detailed comparison, pros and cons of each etc. 
I recall the site colour scheme was lots of reds and yellows, very vibrant, but I cannot find it now. Any suggestions?

Might it have been snapsort dot com? 

This one ?

Not exactly vibrant, but it may have undergone a redesign. 

There's also this.......

Although if you type in google (other search engines are available) for example Sony A7iii vs Nikon Z6 there are a few websites that do this type of thing e.g.
