Was never impresssed with Paul Bissonette. He fought to not lose and had this never fight at away games thing going on. His personality was the only thing that kept him in the NHL as long as he did. Can't hate the guy though. Glad the media career is working out for him and his knees.
Troy Bodie sucked at fighting but was willing. Connections played a role in him even reaching the NHL.
Kevin Westgarth was a huge disappointment after his AHL stint. Got ragdolled by Scott and did little else in the league fight wise. There was a lot of hype surrounding him in his first season.
Krys Barch was a poor mans Thornton who lost nearly every fight. Had some doozies with May though.
Hal Gill was the worst fighter I have ever seen, 6 ft 7 and threw pillows. I think most posters on hfboards have a good chance at getting him at a draw atleast.
I always thought Bissonnette was pretty conservative when he fought. Rarely opened up to trade, and I always got the feeling that he wasn't really intimidating anyone. Never really threw a ton of big hits and just didn't have a very aggressive tone to his game. That said, he always stuck up for his teammates and he was a generally decent scrapper. It always felt very business-like with Bissonnette, for better or worse. He doesn't belong in the conversation about worst enforcer, though. He was a legit heavyweight and he stood in there against some big names, as frustrating as his conservative style was. I'm happy to see his success in hockey media. He's got a great personality and has clearly kept up with the game post-retirement.
Troy Bodie wasn't a good fighter but I always liked his game. Wish he could've stuck longer but he wasn't super fast, didn't provide much in terms of consistent offensive production, didn't really kill penalties from what I can remember (I could be mistaken), and again just wasn't an effective guy with the gloves off. I never thought of him as an enforcer anyway, though. Closer to a Brian Sutherby who couldn't fight.
Westgarth's NHL career was really short-lived at less than 200 games played. Got edged out of LA by a quicker, more versatile Kyle Clifford. Sort of bounced around for a few years after that but he couldn't skate even by enforcer's standards for that time. He was the prototypical clutch-and-grab era fighter. Couldn't handle the speed of the league and wasn't a great fighter compared to how he did in the AHL.
Barch stood in against literally anyone but he lost quite a few scraps. He seemed to lose punching power pretty quickly into a fight, but for as much as he lost he was a formidable opponent, especially earlier in his career.
Stortini goes down as the worst enforcer that I can think of. He deterred literally nobody and lost a ton of fights. Threw forearm shivers about as often as throwing actual punches. I honestly felt bad for him watching him fight. You could tell he more or less understood that he wasn't coming anywhere near the NHL if he didn't fight. It's a tough job and for as game as he was, he's the worst enforcer I can think of. Apparently he got better at fighting later in his career in the AHL, but I haven't done a ton of research into that.
