£1k-£2k road bike input

I've been doing research lately to double my bike collection by adding a good mid-range road bike to the stable. I'd like to buy new, and somewhere sub £2k (ish) range. I have a few criteria or preferences, but am open to being told either of these are silly or pointless, and open to other considerations. I'm basically looking around for options that offer a well rounded package (no entry level carbon frame with Claris groupset), and that offer the best value and 'bang for buck'.

Here's a few of my shortlisted candidates, with approximated price:

BMC Teammachine ALR One 105 (£1,400)
BMC Teammachine ALR Two 105 Disc (£1,900)
Cannondale Caad13 105 (£1,600)
Cannondale Caad13 Ultegra (£1,900)
Cannondale Caad13 105 Disc (£2,000)
Bianchi Sprint 105 (£2,000)
Bianchi Sprint Ultegra (£2,200)
Specialized Allez Sprint 105 Disc (£2,200)

The two Bianchis are carbon frames, all the others are aluminium, but I'm not considering frame material very important. I'm also not sure if disc brakes are worth the investment in this category, but would love an Ultegra groupset. Aesthetically I am not too fussed, although I definitely prefer the horizontal top tube on the BMCs and the Cannondales. My two favourites so far are the BMC ALR One because of the price, and the Caad13 Ultegra beause of the Ultegra groupset.

Any other suggestions I should check out?

Have a look at Canyon, as you'd get a lot more bang for your buck in terms of groupset and components

Decathlon seem to offer good bang for buck on their bikes if you're not fussy on the brand name

E.g. https://www.decathlon.co.uk/p/ultra-cf-ultegra-carbon-road-bike/_/R-p-301058

second for Canyon
Endurace 105 disc
Ultimate 105 Rim if you want discs it is just over your budget at £2199
but Giant also are pretty good value
Contend SL 1 Disc

Ha, third for Canyon. I've got the 105 Ultimate turning up some time in the this lifetime.

Be prepared to have to wear celeste if you buy a Bianchi... it's the law!!!

If you look on ebay here are some good deals if you know what you're looking for in terms of size and brands.

The Van Rysel rebranding certainly helps. Ultegra and Cosmics on a decent frame for £2k is not bad.

Allez sprint disc - super fun
