VAC IS A JOKE LMAO

Alright, i wanna say is that i do not cheat in cs:go. I dont find it fun, and dont completely understand the appeal to it, but if you like it.. I wont stop you.

Now about your question, VAC is ok, like just ok. Its gonna ban a lot of people if they are running a program that changes shit that it would consider bad. You could be running cheat engine and it would ban you (which kinda sucks). I feel like overwatch is a big deal tho. People like doing overwatches, and help out. This also makes hackers be less blatant and therefore harder to get caught by overwatch (which they are scared off) but it also makes them hack less so people have a more fun time. So if you have an undetectable hack, and you have skins and are in high division you are not going to spinbot round 1-16, but rather use walls, and maybe slight aim. Overwatch and vac together make the game much much better than it would be without them, yet they are not perfect whatsoever.
