I remember your CRAW findings, Stan, and that made me skeptical about using it initially. But I've found at least for my uses, like events and sports coverage, that the image quality tradeoffs are generally unnoticeable and I'd rather have the performance benefits, such as deeper buffer depth for sports.
A while back I'd shoot regular RAW for most other things, such as my event work, then after a project is done, I'd run at least the outtakes through Adobe's DNG Converter to apply lossy compression and knock down storage size. But those converted files aren't (or weren't - I haven't revisited to confirm) Adobe Denoise compatible. But Canon's CRAW files are Denoise compatible and I haven't noticed any other incompatibility with them in LRC, so now I just default to CRAW from the outset unless I think an image or project will benefit from lossless RAW compression.

Normally I would use the R5 II in EFCS and CR3 for single shots at low ISO, but shutter mode makes less difference with the R5 II. It's easy enough to switch between a 20 or 30 FPS setting in ES with cRAW and a single frame or low FPS with CR3. The buffer doesn't last very long at 30FPS in CR3.
There are plenty of reasons to dislike Canon cameras, but I don't think the FPS or RAW modes is a dealbreaker. Lack of a pro body with more than 24MP is the elephant in the room.
I don't accept Adobe ACR and recall there were some issues with various software not fully suporting the cRAW, e.g., did Capture One get the cRAW working properly?

I'm not disliking Canon cameras, at all, there is apparently a major advantage, here, maybe I'm saying it wrong. The R5 II has a major advantage over the A1II, since it does true 30fps in full raw, and the A1II doesn't, unless you use compression
I am irritated no one serms to be talking about this much on FM, at least I haven't read it and kinda had to dig it up myself.
Canon says 93 raw, TDP got 161 or something but nothing on the frame, so i'm not sure if the files are full sized as far as MB in he TDP test. I'd be curious how many you get, doubt I'd hold the shutter down even 3 sec anyway and it apparently clears very fast.

RAW buffer depth is very dependent on factors such as subject content, lens focal length, aperture used, ISO, card type and write speed. Particularly ISO because as it increases, files, whether lossless or lossy, can't be compressed as much as lower ISO files. Therefore, to maximize 30fps (R5II, R3) or 40fps (R1, R6II) usable buffer depth, lossy compression is definitely a real-world solution because even with the R5II and R1, buffer depth is somewhat limited at highest fps with lossless compression. I have definitely hit buffer limits during long bursts when covering extended plays during sports events. But sure, not everyone is going to experience this and it's dependent on what and how something is being photographed.
It's also a somewhat academic argument because, for example, a significant percentage of photographers working sidelines at sports events are shooting in jpeg where RAW buffer depth is no longer a factor.

(If as rumored, DJI enters the market, that might change.)
