I love mine. I have two of the lenses in your poll (RF 28-70/2 and RF 24-105/2.8). I also have the RF 24-105/4L and I used the EF 24-70/2.8 II for nearly a decade (and had the EF 24-105/4L IS before that).
I didn't get the RF 24-70/2.8 IS mainly because I started with the RF 24-105/4 (bought with the EOS R in 2019 though the 1D X remained my primary camera), and when I transitioned fully to mirrorless with the R3, I bought the 28-70/2...then it just seemed too redundant to get the 24-70/2.8. But the 24-105/2.8 resolves the quandary of being forced to choose between a more useful focal range and a wider aperture. On top of that, the IQ is great, the AF is fast, and it handles well.
My only complaint about the 24-105/2.8 is that the tripod collar is not removable. The foot comes off, but I want the ankle gone, too. I did preorder the RRS replacement foot for the lens, which I suspect I'll prefer to the Canon foot with a lens plate...but I rarely use the lens on a tripod anyway.
The 24-105/4 is my standard zoom for travel (for which I take the R8, not the R3). But for everyday use, the 24-105/2.8 is my go-to.
