Awesome gimmick, I marked out for it hard every single time. I'm pretty sure Triple H bit the water spray thing off of Gangrel's entrance. GOAT theme song, perfect look. Bloodbaths were some of the coolest shit going in wrestling at the time.
As a worker he was a solid fundamentals kind of guy, but the whole point of The Brood was to get Edge (and to a lesser extent Christian) over so as far as that's concerned he pretty much played his role perfectly - he was the "leader" of the faction but gave most of the shine to the young guys. Honestly I think the guy was underrated as far as how big of an asset he was, pretty much the model of a good veteran wrestler.
