Brake pads, ceramic vs semi-metallic

[Land Yacht]

Trying to decide which to go with, main concern is rotor wear. I see differing opinions on the internet, was wondering what your personal experiences have been? I put new rotors on my truck with ceramic pads and after 3 years, ~40k miles, the rotors are too thin to have turned. Have not seen that kind of wear with semi-metallic pads.

thanks-

edit- The rotors were generic parts store Chinese issue, but for all I know buying them from dealership would have been the same quality at 2x the price.

My only experience with ceramic pads was on a F-150 truck.  The pads were so noisy, I took them off after a few days.  Replaced with  semi metallic

I use nothing but semi-metallic on everything ...Gets the wheels kinda dirty but does not ruin the rotors ...
I just completed pads & rotors on all the "daily drivers" here in my fleet....( WHEW $$$$)

It is VERY important that the pads & rotors get "bedded" properly when installed ...

Thanks guys, Will go with semi-metallic. Napa doesn't carry them anymore for my truck, O'Reilly still sells them. I hear they are phasing them out due to environmental issues, mainly zinc/copper that they claim gets into stormwater run-off from the roads.
