A++ Vector software is very easy to use and has been amazing so far. Currently have played 23 games with vector. 18 W- 5 L, 30% HS. and so far no issues, no suspicions, and no accusations.
The support team is great. Fast response time, and will help you with your initial arduino setup as well as any issues that may come up along the way. Discord is active, has a active ticket system with fast response, and has many different user-submitted configs to try.
Would seriously recommend vector software if you're in need of a UD arduino aimbot.
