Canon EF 24-105 vs RF 24-105 both F4

What to get? I just got the canon R8 and am debating between the ef and rf version of the 24-105. The price difference is 400 eu for the EF and 800 eu for the RF.

Should I buy the RF version and use my old 75-300 ef for zoom. Of buy the EF version and have money to spare for the 70-200 L EF.

I will probably only need the range 200mm+ on my trip to Norway next month, besides that I mainly shoot street photography.
