Should I upgrade my 17-55 F2.8?

Hey guys, I have a quick question about upgrading my EF-S 17-55 F2.8, u got it when I got my R10, but now I'm thinking on upgrading it you tho RF 14-35 F4 OR THE 15-35 F2.8? I feel like it's time to upgrade it, mainly because the auto focus, and because now I have a FF camera ?

If I upgrade it, Wich one should I chose, I'm personally leaning towards the RF 14-35 F4, mainly because the weight, the cost, and I also have the RF 24-105 F4, and I wanted to see if it was good option again the F2.8
