[Closed] Planet-X SL going, new bike time,which one?!

Hi
I’m looking at upgrading my Planet-X SLPro soon and have a shortlist. I’ve entered a few sportives & triathlons this year, and quite like the idea of maybe doing some time trials.

Canyon Aeroad CF8.0
http://www.canyon.com/_uk/roadbikes/bike.html?b=2516
Love the looks & spec of the Canyon and have read some good reviews, but not able to ride before buying.

Scott Foil 20

The Scott seems to fit the bill well, but have read can be a very harsh ride?

Kuota Kharma Ultegra
http://www.epic-cycles.co.uk/Kuota_Kharma.html
Kuota Kebel Ultegra
http://www.epic-cycles.co.uk/Kuota_Kebel.html
The Kuota looks the part, and good spec but hard to find too many reviews on (&maybe heavy?).

I know the best way is to ride a bike to see which is best, and I plan to visit Epic cycles as they have Scott & Kuota, but not able to do the same with the Canyon. Obviously ride is king, but I think you need to love the bike too to inspire you to get out on it, which is where the looks come in.
At a budget of £2.5-3k how much better are these likely to be in the real world to my PX and any others to add to the list?
Ta!
