What are the exit row seats like on QF flights. Specifically I've booked the following seats on the following flights and just curious what people think as far as if they are good seats or not. Seat guru was somewhat vague.

QF545 - Brisbane to Sydney - Seat 34B Exit Row
QF626 - Melbourne to Brisbane - Seat 14 C Exit Row
QF417 - Sydney to Melbourne - Seat 34B Exit Row

I assume the two flights with the same seat are on the same plane type. Any feedback is appreciated.
