...multiple styles of animating
You mean like ease-in ease-out, squash and stretch, animating on 1's, animating on 2's, camera movement, crowd scenes, walk cycles, run cycles, etc...? I'd think that just about everyone is working towards improving those aspects.
Anyone who says they've "mastered" animation is an outright liar. There's always room for improvement - everybody can give 110%, and learn from their mistakes for the next film.
If you're talking about Anime vs Western Animation vs Noir vs other "styles," then I think it's not really ever been all tried by one animator. (Apart from, perhaps, Dylan Woodley) And even then, I'd argue no one's "mastered" it.
Some brickfilmers I think have beautiful animation and have mastered intriguing storytelling - that's another question entirely - but, for that, I'd choose Nathan Wells, Doug Vandegrift, Zach Macias, Philip Heinrich (Smeagol), Shelby Pritchard, William Osborne, Keshen, FancyPants, DarthMilo, Jay Silver... the list goes on. Although, I'm sure (to themselves) they're still looking to improve their craft, whether that's improving animation, workflow, or some other aspect.
Beast is still one of my favorite brickfilms, but I can see the improvements (technical and non) by Driven... And, of course, the evolution between Driven and 30 years... And then 30 years and Meek and the Bold... and so on.
