Austin is a step above Angle as a worker.
Angle started his career with plenty of potential but by the 2003 Rumble, he stumbled upon a formula and stuck to it. Now the majority of his matches, no matter who his opponent is, is Benoit/Angle 2003 and it's just so mind numbing. Kurt doesn't have any idea about face/heel psychology and his selling can really suck at times too.
Even when Austin was working with a bad neck, he was still working some of the best brawls/sports entertainment matches in the world. His work against Dude Love, Vince McMahon and The Rock rank right up there in those regards and when he made his 2001 comeback he was arguably the best worker in the company working classics with the likes of Triple H, The Rock, Kurt Angle, Chris Benoit, Chris Jericho, The Undertaker etc. etc.
