Well here is my take on it.
When I looked at alternatives to replace my Honda E. I found the Yaris Cross a bit cramped for me and not much else offered the practicality of the Jazz. Honda E was great, but limited range in the winter and practicality were the reasons for the change. The Clio does look a viable option, if a bit less interior space and practicality works for you.
I have a second large SUV and the Jazz tends to be used as my city car, where it excels. From time to time I have travelled on motorway journeys, airport and back of around 140 miles. Whilst I dont find the seats as comfortable as my SUV, its absolutely fine on the motorway, as quiet as many other cars I have owned and driven, never found it lacking in keeping with the traffic flow at anytime to motorway speed limits. My motorway consumption tends to average around 60mg on such trips.
Unlike others, I dont see the brake issue as a particular problem for me, simply I won't own a car with todays prices for repairs/parts without buying an extended warranty once the main warranty runs out.
Of course buying a Jazz, immediately puts you into a certain age group
