Re: R5+100-500+1.4x or R7+100-500?

I have the R5 and 100-500, and very happy with the combination. I also have an R7 on order but now I'm wondering whether anyone has done a comparison between the R5 with the 1.4xTC (giving 700mm max FL) and the r7 with the bare lens (giving 800mm effective max FL). I do understand the issue with the TC restricting the short end of the zoom range. I've also tried crop mode on the R5 (17MP) and the results are mostly good but would like the extra sensor resolution. My feeling is that the r7 should have the edge, bearing in mind of course the differences in noise, which I am happy to deal with in RAW conversion (DXO) or in post (Topaz). However the TC would be less expensive...700
Thanks for any examples or pointers towards other sources.
Haven't seen any conclusive tests yet, but R5 with 1.4x has approx the same number of pixels as bare R7 when R5 cropped to same FOV, so I'm expecting similar resolution in real world use.
If I add an R7 to my R5, it will probably be with an RF 100-400 for a smaller walkabout rig, but even then I'm hesitating because I think I'll always be wishing I'd brought the R5 with me instead.
This is pretty much what I’m thinking, but would like to see an actual comparison of IQ between the R5/1.4x/100-500 and R7/bare 100-500. The R7 will also be useful as a nice travel/cycling/hiking camera with a smaller lens set (10-18/18-150/100-400).
The 1.4 get you a 700f10. That is not quite as good as the R7 when doing exteme cropping it may give 6000 pixels on the subject while the 2X gives 12000 pixels comes out sharper and very close the R7 with the bare 100-500. The R7 works when you only have a few pixels on the subject in a 32 megapixels image. If you do not crop any or much then the R5 puts more megapixels on the subject.
I have shot hundreds of test shots comparing the R5 and R7 image sharpness. You need good light and a steady tripod/camera since these longer FL are sensitive to vibrations and having enough light on the subject.
