It's more than just that. Poor ride quality (which going to CAF won't solve!), excessively bright lighting, lack of luggage storage space (although that's been improved recently)
All of those bar ride are interior design matters which would presumably be specified pretty much the same on the CAF units, and CAF units ride worse than 80x by a considerable margin.
I'm surprised that people criticise 80x for ride when they've had Mk4s before, though. Mk4s are the only stock I've been on where the ride got so bad at one point that I genuinely thought we had derailed, and if the heavy vertical vibration (repeated movement of at least a few centimetres) had carried on much longer I was giving serious consideration to pulling the handle as I was starting to think that a wheelset had come off. I have never had that feeling on an 80x - they are a bit "hard" but essentially the same as Desiros in ride terms - indeed the whole package feels rather like the "Class 344" I've long commented about wanting to see (as does the 397, to be fair).
not to mention the way too frequent short forms which have regularly occured ever since 5 car 80xs entered service with LNER, and have become even more common with the recent cracking issue.
Solving that isn't (cracking aside) an 80x problem, it's a "not enough stock" problem.
