Which is better gauge mates or chamber mates for shotgun gauge reducers?

I have the Gaugemates for 20 and 12 shotguns 12-16, 12-20 and 20-410. They work good and won't crack, they are made of Stainless Steel. Cost less than 60/pr. The only problem is time, time to get out the shell out from the reducer. Best reducers were the Savage, I have 12-410, they don't do them anymore. Gaugemate have the gold ones, those will take the shell out with the shotgun's extractors. They are so expensive that is better to get extra barrel or even a new shotgun. I don't think the gold are worth it.
