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...
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.
I have both R7 and R5. I will bring the R5 on an important shoot in an unknown environment. Maybe I bring both if it is import enough. However which tiny subjects do not have feasible shooting near full frame. The R7 is the king where tiny subjects that hard to get close to. Shooting bugs and much of macro photography can benefit from the R7. I have help from the EF 180f3.5 macro and a 2x TC at times. The R7 will be handy in some of these cases.
When walking around or hiking with a need for telescopic lenses the R7 will reduce the weight of both the camera and lenses vs the R5 in many cases. FF gear gets heavy when you carry it all day.
The R7 with the RF 100-400mm (640 FF equivalent) has more reach than the R5 with the RF 100-500 and it roughy weighs 1lb less.
I will decide case by case which camera and lenses to bring.
