I will contend that X-Pac was the best worker of the Attitude Era until the Radicalz jumped and Kurt Angle found himself. In 1998-1999, he was the best. And he was over as FUCK. Second most over babyface depending on what Rock was doing. Even ended house shows and a PPV doing the beer bash with Austin. X-Pac heat wasn't a thing until he turned on Kane and DX reformed as a heel group that kill everyone but HHH's momentum.
All entirely true.
Kid's initial run was also completely fucked by his heel turn. 1-2-3 Kid was maybe the third most over babyface in 1994 and fourth or fifth in 1995 before he goes heel.
