I mean, if your only concern is winning then just look up some guides on what is considered the strongest build right now. Or just stick with DK.
On the other hand, if you actually enjoy the process of coming up with builds and trying out ideas just to see what they end up as then pick whatever. Admittedly, I don't think that freedom of builds is anywhere as near as good as it used to be since multi-classing became a thing. But at some point, every class is going to end up being the most broken and overpowered thing in the game anyway so it's not like you will never use anything you make right now.

All of the other classes have had their day in the sun. But with subclassing, the only class that matters (currently) is Warden because of their class mastery script that includes Charm. My personal choice has always been DK because I like the melee/brawler style of gameplay. Right now its a top class, but that will change as it always has and always will. But I also like NBs if I feel like ganking or bombing.

Arcanist leans AoE, but I wouldn't pick Arc for Our Fake PVP unless you really want to, it's a bit difficult to make shine. The Real PVPers might do Arc better if you wanna try and get into West Point to learn from them. 🤭
Overall Warden is the next best class after the outrageously and absurdly OP - for now - DK, even without the Charm that we all hope is soon deleted. Warden still has the single best healing skill and the single best damage skill, pretty sure, in Polar Wind and Deep Fissure.
Warden is also the thematic counterpart to DK, with many of the same general underlying mechanics. So if you have experience on DK but want to try something else that doesn't make you look like an exploiter, and you have a bad taste left in your mouth from errant Blastbones running off to disintegrate in failure, try the class with the superior ranged delayed burst AoE.
Try Warden.
