I find the ratsnest very useful, particularly used in conjunction with connection swap and back- annotation to the schematic. But then, I'm usually tracking microcontroller and/or PLD designs for logic. It lets you optimise positions and pinouts for easy routing before a trace is laid.

complete and I have to undo sooo much that I haven't used autorouting in the
last five years.

That's not unusual. All but the most expensive autorouters need lots of spare PCB.
