I've been using burn for probably over 3 months now and it's been amazing. It's extremely good for rage hacking when you need/want to, and when you turn the smoothing to max and play legit it's pretty good for that too. I haven't used zeta myself, but whenever my friends try and use it the prediction is usually better on Burn (they usually complain that they can't hit certain shots while I can, but they might just be bad, I haven't used zeta to test it.) I've bought burn like 30 times now and I plan on buying a month of it soon. 10/10 literally no issues from me. I have also never been banned using burn.
