MorphOS but that is not the best for debugging as there's no source available nor any help from its owners but just to see if it boots it may be sufficient, it should work on real PowerMac G4).
I have no idea what MorphOS uses, but I bet HPT as well. That is because HPT is fastest in general. Software TLB reloads are good in special cases only; the most common is real-time OSes, which can use its lower guaranteed latency for some special address spaces (and can have a simpler address map in general).
