Switching back to R5... help needed

Hi,

Currently I am a Sony shooter. Generally I shoot wildlife + live gigs so i have a pretty complete set of lenses:

- 16-35/2.8
- 24-70/2.8
- 70-200/2.8
- 200-600/2.8

+ A7r3 and A73
Background:

To be honest Sony has its advantages (like general AF performace, fact i own all needed glass...) but is still missing some important things to me. And I wanted and upgrade byt a9 is no go as it doesn't have antiflicker and very slow mechanical shutter, a92 is ok, but no bird-eye-af, only 24 mpix sensor, crappy menu and is more expensive that r5. There is alsos A7r4 but... 60+ mpix is little bit to much for me and I had some issues with 200-600 when checking couple of bodies in the camerashop - focusing was not accurate - even when using tripod. A1 is little too expensive for me.
There is also 2nd thing about Sony - I don't trust it in 100%. I had one of my body replaced by the service, 200-600 was fixed as it had some issues with consistent focusing, I am not telling about shutter and shutter button replacements - definitely way to much for such expensive gear. So in short words: good gear but i don't full trust it.

And here comes the R5...

It has some great features like bird-eye-af, 12fps mechanical, 20 electronic shutter, anitflicker and 45mpix sensor. I think that i would like to start my switch from the wildlife end and have couple of questions

- Is rolling shutter that bad on ES?
First about 200-600 replacement

- doest it make sense to go with Sigma 150-600 Sport or maybe Sigma 60-600 Sport or even Sigma 150-600 Contemporary
- can achieve 12fps on mechanical shutter with all these lenses (how is the sharpness) (and which version of 150-600 is better)
I am also considering: 300/2.8 IS or 300/2.8 IS mk2
- can i shoot 12fps mechanical shutter (version 1)
- how well it performs with TC 1.4 and TC 2 (version 2)
RF 100-500 - is little to short in long range and to dark - usually shoot around 400 - 600)
Other lenses are easy to replace 1:1 with RF versions.
Or maybe i should visit some specialist - overcome my lack of trust to sony and just wait and or get A1 in the future or a93 etc

I have be using electronic shutter on the R5. It is much less than the EOR R. The R6 is better but R5 measures only 16msecs. The A9 is faster at 9msecs which better and the A1 is supposed to 5 or 6msecs. I have shot more the 10,000 stills using the R5 ES. I love it and have found zero issues with rolling shutter in the real world. It is not problem for me and the ES is magnificent and works at 20 FPS will all my lenses old and new. I know if find some special case like bad lighting the R5 has 12 mechanical which really fast even when slow down for tracking or autofocsus. I zero concerns in my use for rolling shutter. I do not care about more than 20 fps. This is plenty fast form me and sometimes too fast producing too pictures to go through.

I know the RF 100-500 is a magnificent wildlife lens but I use wildlike mainly the EF 100-400mm Mk II with the 1.4X and 2X Canon Mk III TCs that I had before the mirrorless cameras ( 5D Mk IV and 7D mk II). I have the Sigma 150-600 Contemporary with the 1.4X and 2X Sigma TCs as a alternative lens. I like both but the Canon 100-400 II is usually my first choice even though the maximum FL is shorter than the Sigma. The 45MP of the R5 allows for more cropping than my earlier cameras.

I also have the EF 400mmf2.8L IS but is a monster. Do you really have a 200-600/2.8 as this also must be a bigger monster.   I have a Sigma 120-300mmf2.8 but use that more for outdoor sports that wildlife because I usually use it with a monopod.
