All in "micro four thirds"
Full Frame vs Micro Four Thirds
I apologize, that was a click bait title and a very dirty trick. Especially because the two can't really be compared any more than you can compare a pickup truck and a passenger sedan. You are in the market for either one or the other. One will work for your situation and the other will not, at least in most cases.
One of the benefits of having soccer practice next to a Gothic Cathedral is that it gives you something to shoot while you wait for practice to finish. I spent a few minutes the other night taking advantage of the earlier sunset and grabbing some blue hour / night shots around Bryn Athen Cathedral.
