In terms of equivalence, your combo of a 17-55 f2.8 mounted on a Canon APS-C sensor is equivalent to a 27.2-88 f4.5 lens mounted on a Canon FF sensor.
So in terms of total light gathering ability, the 24-105 f4 on your RP is better.
This is of course assuming both sensors use similar tech. I know the sensor in the RP is pretty old tech, but I don't know what APS-C you're using.
