Which bike is the best?

I apologise for multiple posts but I'm reall struggling with which bike to purchase.
I've whittled it down to 3 but just need some knowledge on each bike.

At a push, the Ribble 7005SL Race bike could be afforded but ideally I'd like to spend £700 at the most.
Thanks for any advice.
