I shoot wildlife using a combo of DSLR and Mirrorless and I have to say, I almost always reach for my R5 (mirrorless) over my 5d mark4.
One of the things I love most is seeing exposure in real time, it's a nice little quality of life thing you don't think about until you experience it. Over the years I think anyone who takes photography seriously has gotten pretty good at gauging exposure, but to actually see it change in real time when you adjust ISO or Aperture is pretty slick.
But all of that being said, I'll hold onto my DSLRs forever too- as one person pointed out the battery life is far better and when you're out for 10 hours at a time that really matters.
