i've even seen the harder OEM and Atkins seals cause gouging and chatter patterns on housings. sometimes it depends on air filtration, other times surface prep of the housings and other times lubrication or seal loading issues.
i haven't actually come across a Goopy seal set yet that caused excessive wear but i've only been running them for the past few years.
ceramics and carbon seals are obviously the best at preventing housing wear but they're not exactly the best for boosted/detonation situations. even the toughest ceramic to date is still just shy of the shear strength of the cast iron OEM seals. for endurance n/a applications i usually try to push ceramic, though most people don't like the price tag.

^ Most workshops & individual people do not like the total destruction either
I've sold
hundreds of these from both known vendors to every self professed 'name' here and many around the world, and they ALL destroy housings, plates, turbo's at the slightest hint of 'non ideal conditions'
