I preferred Matt.
He seemed more Alien compared to Tennant's more human nature of them.
Matt definitely had the better companions(In Amy and Rory), despite Rory being the buttmonkey(Until he became the Centuarion). He was still nerfed, but he has access to 2000 years of training, and is downright terrifying(Doctor sends him when he wants to terrify someone).
I hated Ecc., a lot, almost as much as I hate Gen II pokemon.
