El Hijo del Santo: Easily my favorite ever. By looking at him, you'd next expect him to be as graceful in the ring as he is. Man can also brawl like fuck. I've never seen him come even close to half-assing it before, either.
Chris Benoit: See pegasus's answer.
Blue Panther: Greatest mat worker I've ever seen.
Combat Toyota: I've written about her once or twice before. I have this weird attraction to her and her work. You all need to watch her Big Egg match with Hotta and her FMW match with Kudo. She's so awesome as the big girl who's not a monster.
Val Venis: My favorite wrestler in the E besides Benoit.
Stan Hansen: Such a bad ass.
The Destroyer: Awesome, awesome wrestler.
