Scanner reliability is yet to be seen but it's likely that the
stand alone units will be very reliable since they don't have any
moving parts or openings to get jammed. If the gates are open you
need to remember to scan your card at a validator. That requires
learning a new habit which wont take long for most people.

It'll take more than a new habit to solve the problem at Stratford. At
Stratford, it currently records an "incomplete journey" if you change
from the Central line to the Jubilee line (a change which requires you
to go through a set of ticket gates). Last time I was there I looked
around for scanners to do something about this, but I couldn't see any.
