The Z9 does mostly everything well, but the R5 has the better AF & is waaaay lighter.  Sometimes I just need something light to get-in & out.  R5 will be the BCAM in my studio shoots & as well as the backup for events since I need 2 cameras.  I do prefer the R5 as the primary when doing portrait stills due to color science. 
 

I can confirm the R5C AF is not up to the task.  I wasn't expecting it to be so bad.  Couldn't reliably nail focus on simple subjects.  The R5 runs circles around the R5C AF wise.  I'd rather deal with the overheating on the R5 then the AF of the R5C.  I sent mine back.  I loved most everything else about it.  I'll have to go dual system with the R5 & Z9.

I think we've just gotten spoiled with the latest batch of cameras.  I was planning on picking up the next Black Magic Pocket when it included 8K but going to add the R5C to go with my R5.  Had both the BMPC4K/6K and enjoyed them but the autofocus of the Canons won me over.  
Love the flexibility 8K gives me in post for stabilization, cropping & zooming.  Basically can leave the long lenses at home.  As far as the R5C missing IBIS, it is unfortunate, but what Cinema camera has it?  Plus I'm thinking the lens IS & EIS would still perform better than the IBIS from the latest Sony cameras.  Canon probably should have called it the C5 to hammer home that it's a cinema first camera.

So I can get 30 min 8k raw with the latest firmware on my R5 with crappy heat dissipation and Sony is giving you 30 min with superior heat management, less resolution, 420 and only 400Mbps.  The R5 bitrate is 2600mpbs & 1300 for HEVC, so that lowering the bitrate option should help significantly with the record times.   Really puts in perspective how versatile the R5 is, even though they blew the initial execution.  Glad the Canon pushed the envelope and Sony answered.  Looking forward to see what the new firmware bring...

Gave my R5 a workout a few days ago.
Outside Temp 59F, Shot varying 8K Raw, 4K HQ/HDR 30s - 60s clips at a park.  The RF 50 1.2 AF is loud AF.  Wasn't expecting that with a 2300 lens.  Where the nano USM?  Over the course of 2 hrs got the timer down to 5min but not even a overheating warning.  Not expecting that when summer comes back around.  I was able to shoot until the battery ran out.  I was able to get by with just 2 batteries on my A7III for an entire day, but that's not going to be the case with the R5 going to have to get more than 2.  Loving the 8K RAW/4K HQ footage.  Finally a camera worthy to my NX1.  Really impressed with the HDR PQ, but couldn't get it to play back on my HDR TV via USB.  Viewing it on the DPP software is stunning.  Now I need a resolve workflow to keep the HDR PQ & metadata when I render it.  
Just my initial observation...

My NX1 is by far my favorite.  It's like Samsung reached into the future and brought that camera back.  Paired with the 'S' Lenses it can go toe-to-toe with any camera on he market today.  The level of detail is astonishing.  When I deliver at 1080p my clients are amazed at the quality.   Have not been blown away by any camera yet and will continue to use my NX1 for video.  A7III video is good but nowhere near the NX1 so it's been relegated to stills & B-CAM.

NX1.
Except for AF and Rolling Shutter issues, perfect camera with incredible form factor. I really wish Samsung had given it one more go!
