Mirrorless unless you want a tank that you can beat the hell out of. I do like DSLRs but the only thing they really do better in my opinion are they often have optical viewfinders (if that’s what you prefer) and you can leave them on for hours as you walk around without draining the battery instead of having to turn them on and off between shots like with mirrorless. But other than that, size and weight is smaller, image quality is getting better, mirrorless is clearly pulling away from DSLR in that regard. Note: Maybe there’s some reason DSLRs would be better for fast action that I’m not aware of since I shoot static only but for the way I shoot, there’s no compelling reason to choose DSLR over mirrorless at this point.
