Is Windows 10 Creators Edition really safe to use?, such as do I have to worry about privacy or telemetry features, when I keep reading things at this place, people keep saying different views of privacy so I always feel it is never safe any more Windows 10. I own a legit version of Windows 10 Home and is there any point of upgrading back to it? currently I downgraded back to Windows 8.1 (Core) because I thought its safer in the longer run lol .
W10 is safer than W8.1, more security features build in. However, yes, there is more telemetry in W10, but you can turn almost all of them off, so for me not a problem.
Depends on what you mean by safe. If you are talking security it is the safest version of Windows so far. If you mean privacy, if you are connected to the internet with any OS you already lost that battle. And if you carry a mobile phone, even worse. I have upgraded multiple machines (all of mine and most of the ones at work) with the Creators Update for Windows 10 and have not had a single issue with it. Not a crash, BSOD, or issue of any kind. If you are going to run a Windows PC, I recommend it over any other currently supported version of Windows. Like anything else, my experience may not be yours, but in general I find it very stable.
