Short Career, Biggest Impact, Most Success?

I think Warrior had the biggest impact on Wrestling of the 3 mentioned. He was arguably just as popular as Hogan was in Warrior's heyday (1990-1991). His stuff still sells well to this day and many people will know his name is you randomly ask people on the streets. However i don't consider Warrior's career to be short.

However, Brock had the most success for his small 2-year career. He did everything someone could do in the WWE in those 2 years; Won several WWE titles, won the Royal Rumble, Main Evented WrestleMania, King of the Ring, pinned the likes of Rock, Flair, Hogan, Taker, etc.
