Oem head gasket or aftermarket which is better?

Well my '10 @167k miles had about 4 seconds of misfire twice on one long drive after a start up and light acceleration.
I thought: Spark Plug time... Nope. Checked the next morning and the coolant was down 3/4". Topped it up. Went for another 500 mi trip.
No misfiring, but it used 3/4" of coolant again.

I now know: Head Gasket Time.
I'm driving it 220 mi to Gasket Masters for a one-day $2000 repair and they only use the FelPro! It gives me hope, but only time will tell.
With this service they replace the Spark Plugs and PCV valve and use previously cleaned Intake and EGR parts. I'm hoping I get the later model intake, but that's not important to me.

 

I wonder when the foam will start to fall apart clogging all the coolant passages and heater core
and radiator?????
