Reliability is a wide topic. 8.2 reliably works as intended, though 8.3
certainly has better "intentions" as to how things *should* work. I
would say that 8.3 has fewer "unintended consequences" for the average
user and a ton of benefits:

If your definition of software reliability includes good behavioural
characteristics as well as absence of bugs, then 8.3 is a must.
