Titan Master: Honestly I think I have to go with Fangry. Crashbash is fabulous in dino mode but to me, his dragon really leaves something to be desired, while Fangry is pretty great in both. (We don't speak of weapon modes.)
Legends: This is a little tougher to choose, but I think Wheelie takes it for his incredible look in both modes and creative transformation(I love Bumblebee but I can't really argue that he's objectively the best). Gnaw gets an honorable mention because every few hours I look over at him and his buds and go "oh my god I have actual Sharkticon toys on my desk my life is complete".
Deluxe: Hoo boy, this is the hardest one. I happen to have all the Deluxes up to Wave 3, so there's a lot to choose from, but... Hot Rod. He's not even close to the most refined of the TR deluxes, but I think he just might be the most fun. His antithesis, Triggerhappy, comes close but despite being incredibly engineered I just don't feel as compelled to pick him up and play with him. (And in a presumably rather unpopular opinion, I think I'd actually rank Getaway above Chromedome in the full list if I'm being honest.)
Voyager: Astrotrain, no doubt - his only competition is Broadside (who might as well be a dual-changer to me
) and Galvatron, who's cool because he's Galvatron but not good for any other reason. I have TR Megatron pre-ordered, so when he arrives he might take Astrotrain's place, but it's hard to tell without having him in-hand.Leader: Well I don't have anyone except Sixshot, and even he's not in hand yet, but I've paid for him so he counts. I'm not going to spring for Sky Shadow, but I'm willing to bet that once I eventually get an Overlord he'll be the new best.
Titan: Fortress Maximus, by default. Yaay.
...Actually no, Devastator wins, because Devastator deserves this place so much more than Max that he is able to transcend lines to become the best TR titan.
I do like him as the big dude who got his ass whooped in Megatron Origins.
