I don’t think anyone’s mentioned geometry in relation to what you want to do with the bike? Ribble’s have long and low race geometry, even the audax and sportive models which is fine if that’s what you want but they don’t always make great all rounders or commuters as a result.
To give you an idea my former 54cm Ribble Audax had a 57cm top tube and short head tube, long and low with toe overlap too, my current 54cm Trek Pilot has a 54cm top tube and long headtube, shorter and taller so more upright riding position. Nothing wrong with either just better at different things so maybe have a think how supple you are and what riding you do?
