Other than Subaru has anyone used any other branded stuff?

Having a flush and replacement done on Monday and not sure if to buy it from Subaru or whether something like Halfords Advanced stuff would be any good to use?

Have done some research and found its OAT (organic acid technology) and does contain ethylene glycol - otherwise known as MEG. Which from what ive read will be ok for mine.

I can pick it up for £20 for 5l plus £3 for 5l of de-ionised water to do the job - assume coolant from Subaru will be more expensive than this?
