In general, things you'd control via subclassing are much more low-level (like Qt's whole event system), and signals are much more high-level. For example, with a QLineEdit, you could override keyPressEvent to get low-level keypresses - or use the returnPressed signal, which works with enter/return, and only emits when the input is valid if a validator is set. But there are certainly some exceptions (usually things which require subclassing which IMHO would be much nicer as a signal).
