I am using a 6D which I absolutely love. I want to get a telephoto lens and I see two options. To get an R5 with a RF 100-400mm or to get an EF 100-400mm mkii at half the price.
I feel like it's just gear acquisition syndrome pulling me towards going mirrorless and my rational thoughts tell me that keeping my camera body and getting the EF100-400mm is the best option?
I will be using it for wildlife and landscapes

If the 6D is performing well and doing everything you want I suggest getting the EF zoom. When it becomes time to retire/replace the 6D you can move to mirrorless, use the RF-RF adapter and continue to use all your EF lenses.

I'm with John, if the camera you own today is providing you with good images and has the functions you need I would pick up the EF 100-400mm.
