Booth. He seem's to be more of a teacher than student of the game. I also think that you'd end up becoming a more smarter and sharper version of yourself under him, too. There's no flies on him, so to speak. Shane would be my next choice. Seem's very open-minded towards training, and the sport in general. That's a huge thing in Boxing, IMO. So many coached have outdated methods/ideas. Lockett is grossly overlooked, IMO. Great coach.
Gary Lockett will be the clear number one soon enough. He doesn't desperately seek acclaim and recognition like Joe Gallagher does regularly, just does an excellent, understated professional training job. His punditry on Boxnation is along the same lines. Top bloke.
One thing that sets him apart from most is that he has been in the ring and been in there at the highest level. Not many, literally a handful, of trainers from these shores can claim that! So that'd be massive help, too.
Gif Gallagher is so good why does he rely on Amir Khans kindness and uses Khans gym, he doesn't even have his own gym! Booth did well with Haye and Groves but who else noteworthy does he train? I dont even know who shane mcguigan is
tony sims is good but I think Josh Leather's trainer Imran Naeem is seriously underrated I personally think he's the best trainer in the Uk
