i use the Eagle one at the end of my routing flow:
first drop VCC and GND vias if you're using power planes, then route chunky power traces, route high-speed / differential pairs, finally autoroute everything else
on some boards, only 3-4 signals aren't power or something tight, but for LED Matrix boards with thousands of criss-crossing low-speed signals and other 'fun' projects with hundred of components (keyboards!), the autorouter is really the only way to go if you want to be done in a night or two

I loved Eagle until Autodesk bought them and turned that product into a subscription. Now, I’m locked out of my old designs. Fool me once, you’ll never get my money again.

Sad but true ... Last time I checked they still had the old standalone hidden on their web pages somewhere ... might be enough to open and convert your projects.
