The last great producer???? pHEEEEW, that's a tough one!!!!
Must be Lenky Marsden for me, way ahead of his time, too much of a maverick in the conservative reggae world, i suppose, great at reggae (check certain 90's sounds on Penthouse), brilliant at dancehall when it used to be innovative, still trying to develop new sounds - not always successful but points up for trying!
I'd say more or less of the same about Sly Dunbar but he just can't be the last great producer!
Difficult to say as many producers mentioned are basically executive producers, like Donovan Germain.
Bobby Digital is definitely one of the last great ones, alongside Fattis (who relied a lot on Sly & Robbie and other musicians/producers, but who injected his own vibes) and Dave Kelly (who rarely impresses in the 2000's. Richard Bell is also in that top list, though he relied heavily on his pool of musicians, all of them also being producers in their own rights (Sly & Robbie, Firehouse Crew, Mafia & Fluxy). At least, Star Trail had their own vibes.
In the UK, hard for me to tell. I'd say Mafia & Fluxy, Ruff Cutt, Carl McLeod and Musclehead, though the latter are mostly executives. Nowadays Mike Pelanconi and Mungo (though they've not reached greatness yet and rely on well-tried formulas).
BDF and Lone-Ark are also tops but have not yet reached greatness, it's basically because they don't evolve in a world where reggae still plays a major part.
I think Fattis 's son has what it takes to become a great producer, unfortunately, how can you become one in a world where such music doesn't sell anymore?
"this new style actually killed the traditional dancehall reggae". "Traditional" and "dancehall" don't go too well together,oxymoron!: dancehall kept evolving for many many years and still does, though way less fast and impressively than it used to, not everyone has to enjoy the current vibes but this is just a conservative point of view. I don't enjoy Corleone's stuff much, to say the least, and feel that his reggae is often a real weak sound but he did some great hardcore dancehall in his time. His influence on reggae was rather unpleasant to my ears, let alone what his followers did.
