I'm a Salamence lover. It's design was the best for me out of those three, a blue dragon with red stripes and wings? You're awesome,buddy :3. To be honest I've never used him but he seems the most appealing to me and I like him better than Dragonite since I'm more of a person who focuses on speed and attack.
Tyranitar was a 'meh' for me since I'm not very interested in Rock Pokemon nowadays and also I dislike how he's slow and has several weaknesses.
