Welcome to the forum!
Not in every way. There are things QK did that KM won't do, and there are things QK made easier for the user than KM does.
That said – KM is modern, up-to-date, and superior in many respects.
I used QuicKeys myself from 1985 until 2012, and I started using Keyboard Maestro concurrently in 2004 – even so the transition of nearly 2000 macros was a bear.
Be sure to look through the transition guide for QK users:
