First: Specialized Allez Pro road bike custom built during 2020. Alloy frame, carbon forks. Was fully serviced two weeks ago. It has a new cassette, chain and straps. The bike has minor scratches and damage from use.
I don’t know that much from this bikes history, it was mostly used for city commuting and some weekend trips. From the pictures it looks good, but it might not have been serviced for a while.

5700-generation 105 has a reputation for poor shifting– The short cable actuation Shimano used for 5700 was pushing the limits of the close cog spacing on the 10-speed cassette, so shifting with 5700 can be a bit imprecise. (For 10-speed, Tiagra 4700 uses a longer cable pull and shifts much better).
The Sora is 9-speed and the slightly wider cog spacing is a bit more forgiving for the short shift cable pull, so the shifting on the Sora works better than 5700. I’d get the Sora.

The MUCH newer bike for the same price is the better choice

Unless you’re getting these for £200 or under i would be looking elsewhere. I’d go for the red one just on looks. There’s no real difference between them that will make one better than the other that matters.

This isn’t just a groupset difference. The Allez changed geometry quite a bit in it’s newest iteration. It’s quite a bit more endurance-focused now with a higher stack, shorter reach, and slacker angles. The newer bike will also definitely fit a 28mm tire. Unknown if that ~07 Allez Pro will.
I’d make sure the bike fits properly first. If you want an upright position, the older Allez may not even factor in. If you want a racier position, you’ll have to see if it can be achieved on the newer model or not.
I had 5700 on my CAAD10. While certainly “affirmative” in it’s action, it was far from clunky thanks to the external routing of the cables (same on the older Allez) – I’d put the groupsets more or less on par.

The red one looks faster so I’d probably buy it

That generation of 10spd shifter particularly with under bar cables doesn’t age well.
