Zekrom is a Dragon & Electric type Legendary of Unova, and to me has the better design from the box legendaries. I just find Zekrom's design stands out a bit better than Reshiram's due to the color scheme more-or-less. As well, I'd say Zekrom is better in terms of competitive, as it has great stats, followed up with a great movepool & decent ability. Plus, the typing of Zekrom makes it better in competitive play too over Reshiram, because Dragon & Electric is a pretty solid type combination offensively. Anyways, I love Zekrom, and was originally going to rank it 5th, but had last minute change of mind and decided to rank Zekrom 6th instead.
