The losses in ferrite rods are nothing to sneeze at in comparison. I 
have used both in ham radio a lot when I was young. I built kilowatt 
level RF power amps, impedance matching boxes and similar gear. Ferrite 
rods in transmitters sometimes became so hot that you could barely touch 
them while inductors wound on some random piece of PVC pipe remained 
cool. I don't remember the PVC type other than that it was remnants they 
sold for pennies in the plumbing department so that was very likely well 
plasticized.

My comeuppance happened when I made a wideband and thus tapered-wound 
inductor on PVC pipe that was very long and I was concerned that it 
might snap off during transport. Fielddays, contests and such often 
required transport. So I took some allthread all the way to the top, big 
washer, cinched it down good and called it a day. HUGE mistake. It 
started to glow and melt the PVC. Luckily next to an open window as this 
stuff can potentially kill.
