Yup, they do 'look' like they should be strong / reliable.

Quite.
However, I wonder if the usage may make the weaker ones fail (sooner)?
I'm thinking the worst case might be a ceramic hot bath tap on a
combi system where:
1) It's always sitting at mains pressure (?)
2) It runs hot.
3) It runs for a long time (filling a bath).
4) It is turned off quickly (ceramic tap creating a surge load as the
water is brought quickly to a halt).
I did buy a couple of 30cm x 15mm compression couplers (not tap
connectors) but they seemed 'too cheap' so I've not used them.
Hopefully the ones I fitted on the (upstairs, tank fed) shower will be
under less stress than the ones on the hand basin and both under less
stress than the hot tap on the sink (higher pressure than upstairs) or
cold on the sink (constant mains pressure).
The ones I fitted on the (awkward) shower were about 6 quid each from
a local plumbers merchant? Could that make them 'good' ones, till I
get round to replacing them all with copper that is. ;-)
