As an example I don't know if I would choose the Tokina AT-X 16-28mm f/2.8 Pro FX Lens over my Canon EF 16-35mm f/2.8L III USM Lens but there is no doubt I would take it over my Nikon Do I buy the EF 24-70 f/2.8 and use it on both bodies, or do I buy an EF-S 17-55 2.8 (Sigma 18-35 f/1.8) and the RF 24-105 f/4? I use the 70-200 (with EF to RF adapter) on my main body and a short lens for my second body when shooting sports. If I buy an EF lens, I can use it for both. The cost for the EF and RF lenses is the same as the 24-70 hv5A.

canon ef 24 70 f2 8 vs f4
