I have the Canon EOS R and it has served me well. I am not sure yet whether I will purchase a R5 or R6.
IBIS is a temptation but that being said the Canon 5-stop in-lens stabilization is excellent and usually sufficient whenever I need it.
FWIW, the price of the R is rumored to go down to $1,500 (from $1,800) before the end of September, the RP is currently $900 and $1K with the non-L 24-105mm lens.
