Swapping default wheels, which is better?

Currently feel like swapping my default wheels on my Ribble, in the past I've had mavics aksium and were fine.

But found these and tempted,

Or

Doing a cycle London to Amsterdam in September, is there any other good wheel you would recommend?

Also what's the difference between fulcrum 5 and 5 lg?
