The vastly better AF would give me a much better keeper rate for candids of kids, and the articulating screen would be helpful for some macro work. The first is more of an issue. However, these just aren't big enough advantages to warrant spending the $2500 needed to trade just the body, or $2850 to trade the body and walk-around 24-105 f/4.
And speaking personally, given what I shoot, I have real doubts about spending that $$, if I'm going to spend it on photography, on another FF camera. I lug mine on my back, usually with two other lenses and a tripod, and it's getting noticeably heavier with every year. I'd be more tempted to keep the 5D for times when I want FF and buy and OM-1 to carry around the rest of the time.
But this year, neither is going to happen.
