Which TCR would you pick?

So I’ve narrowed down my next bike to a TCR. Now there’s 3 different options I’ve seen.

The first one is –

Second –

Third –
https://www.ebay.co.uk/itm/326134761624?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=_htPfqhuRMG&sssrc=4429486&ssuid=fXnT5HIeRQ-&var=&widget_ver=artemis&media=COPY

All around a similar price point so just wanted to get some thoughts.

Look wise I’m leaning towards 1 then 2.
But then what puts me off 1 is that I’d have to upgrade the wheels and older group set.

This will be my first proper bike so don’t want to make the wrong decision.

Thanks in advance!!
