I was never a guy who "needed" Leader class Dinobots. The pre-WFC Voyager size was fine, gets the idea of power and mass across, doesn't take up too much space, better price.
But I am very impressed with the Studio Series 86 dinos. The WFC onward internal line scale makes them seem enjoyably, fittingly massive in both modes. This is one of the reasons I tend to prefer them smaller, because it gets hard to display everyone together without some looking incongruous. (The scaling thing where most Autobots are waist high to Optimus Prime has always put me off, like they're his children instead of his team.)
But by themselves individually and as a team with their fellow dinos, it's so satisfying. I just regret that if they go and make the other G2 dinos I may not be able to get them all (maybe just Snarl and Slag) because of the collective space consumption/demand.
And I'm very happy that they did Snarl despite his blink-and-you-miss-it participation in the movie (of course they could have just assigned him somewhere else if they had to), and that he turned out so well. His stumpy wedge of a dino head, the broad gold tail halves on the shoulders, the great execution of spiky potato dino mode. All I could ask for is some clear pieces like POTP did, but I'm digging it as is. Even with the inconsistent gold and yellow, because the yellow is a nice shade that's distributed enough that the mismatch isn't a dealbreaker.
