Go for the 5, as has better components.
Worth looking at Scott Speedster and Giant Defy, at that price or a bit more - especially if you can find one in a sale.
Get helmet, mini pump, mini tool with chain breaker and spare tubes for the ride. Puncture repair kits should ideally be used to repair the tube at home.
If you can afford a Team Sky jersey, you can afford a better bike anyway
