Best site for builds?

I've just started the game on a high difficulty and was curious as to what sites you guys would recommend to get builds for myself and companions. Usually I'd just experiment myself (and still might), but as I'm playing on a higher difficulty I'd like to make my builds as optimal as possible for the increased difficulty.

I've looked online and there's several different sites for builds but I'm not sure which of them are considered worthwhile to follow or at least get build tips from. Perhaps even a Youtuber who makes decent builds?

Any help is appreciated, thanks guys.
