It is kinda difficult to judge by such a short replay but here's my input:
About UC: He obviously wasn't UCing. There were no signs of UC at all, his movements were perfectly fine. You didn't click the "Tab" key while taking that F11 replay so it was also impossible to see his ping for the whole replay.
About Aimbot: As I said before, it is hard to judge by those 40 seconds. Unfortunately we have no use in your F10 replay because first of all we could only see your point of view and secondly it was very blurrish. The reason you saw him shooting in another spot but still managed to hit you is because of his high ping to you, it's all about distance lag. If you had more evidence then it would be easier for me to judge but I personally wouldn't ban someone for such a short replay.
However, I'll leave this report open and let another GM to take a look at this.
